[0002] In current indoor floor cleaning practices, the main traditional cleaning method is manual mopping. This traditional method can maintain a certain cleaning efficiency for smaller areas. However, when cleaning large areas such as workshops and large venues, this method not only requires more manpower but also consumes a considerable amount of time. Sometimes, multiple mops are even needed to increase cleaning speed, which undoubtedly increases labor intensity and costs, resulting in low overall cleaning efficiency.

[0003] In addition to the manual cleaning methods mentioned above, there are also some large mechanical devices on the market that are specifically designed for cleaning large areas of the floor, such as sweepers and sprinklers.

[0043] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0044] like Figures 1 to 4 As shown, the present invention provides an adjustable automatic cleaning mop, comprising a main frame 1, a sub-frame 2, a mop 3, a fixing assembly 4, and an adjustment assembly 5. The main frame 1 includes a keel 11, a first telescopic rod 12, and a connecting beam 13. Two keels 11 are spaced apart, and two first telescopic rods 12 are spaced apart between the two keels 11. The ends of the first telescopic rods 12 are respectively connected to the two keels 11 to adjust the distance between the two keels 11 in the vertical direction, so that the main frame 1 can adapt to different installation height requirements of the rear side of the electric trailer 6. The connecting beam 13 is connected to the keel 11 at the bottom and is arranged parallel to the keel 11 to increase the stability of the structure. The fixing assembly 4 is arranged on one side of the keel 11 to detachably mount the main frame 1 to the rear side of the electric trailer 6, so that the adjustable automatic cleaning mop can move and clean as the electric trailer 6 moves. The sub-frame 2 includes a mounting beam 21, a second telescopic rod 22 and a bottom frame assembly 23. The two second telescopic rods 22 are arranged at intervals, and one end of the second telescopic rod 22 passes through the mounting beam 21 and the connecting beam 13 in sequence and is connected to the bottom frame assembly 23. It adapts to the height of different electric trailers 6 while adjusting the distance between the mop 3 and the ground. The mounting beam 21 is connected to the keel 11 at the top through the adjustment assembly 5 to drive the bottom frame assembly 23 to rise and fall in the vertical direction. The mop 3 is detachably mounted on the bottom frame assembly 23, which is convenient for disassembly and assembly of the mop 3. It is not only convenient for disassembly and assembly, but also convenient for maintenance, cleaning or replacement.

[0045] This embodiment mounts an adjustable automatic cleaning mop on the rear side of the electric trolley 6, allowing the entire adjustable automatic cleaning mop to move with the electric trolley 6, thus achieving mechanized mopping and washing operations. Only one operator is required to drive the electric trolley 6 to drive the adjustable automatic cleaning mop to clean the floors of large areas such as workshops and venues in a short period of time. This not only reduces the number of cleaning personnel, but also shortens cleaning time, improves cleaning efficiency, and reduces the operator's labor intensity, thereby meeting the needs of efficient cleaning. Furthermore, the adjustable automatic cleaning mop of this embodiment is highly versatile. Its retractable and adjustable structure not only adapts to the height of the rear side of different electric trolleys 6, thereby adjusting the height of the main frame 1 of the adjustable automatic cleaning mop according to the actual installation height of the rear side of the electric trolley 6, but also allows the distance between the mop 3 on the sub-frame 2 and the ground to be adjusted according to the actual height.

[0046] It can be understood that the entire adjustable automatic cleaning mop is composed of multiple modules such as the main frame 1, the sub-frame 2, the mop 3, etc. It has a simple structure, which not only avoids the manufacturing difficulty and material waste brought by the integrated structure, but also reduces the cost. It is also easy to disassemble and assemble, and is also convenient for maintenance, cleaning or replacement.

[0047] It should be noted that the keel 11, connecting beam 13, and mounting beam 21 of this embodiment are made of square tubes or round tubes, which are low in manufacturing cost. The connecting beam 13 is fixed to the corresponding keel 11 by welding, bolts, snaps, or other means. In addition, the adjustable automatic cleaning mop of this embodiment has a simple structure and is particularly suitable for occasions such as workshops and venues with large ground areas that can accommodate the riding of the electric trailer 6.

[0048] Furthermore, an avoidance space is formed on the side of the keel 11 and the first telescopic rod 12 facing away from the sub-frame 2. By forming a recessed or notched area on this side to adapt to the structure of the rear side of the electric trailer 6, collision or interference during installation is avoided, so that the first telescopic rod 12 can work normally without affecting the surrounding structure, thereby improving the versatility of the main frame 1 and enabling it to adapt to various models of electric trailers 6.

[0049] like Figure 12 and Figure 13 As shown, the fixing assembly 4 includes a plurality of fixed clamps 41, which are installed at both ends of the corresponding keels 11, that is, two fixed clamps 41 are installed on both sides of the back of the upper keel 11, and two fixed clamps 41 are installed on both sides of the back of the lower keel 11. The four fixed clamps 41 are used to clamp the upper and lower edges of the rear plate of the electric trailer.

[0050] The fixed clamp 41 includes a first base 411, a pressure head 412, a pressure head fixing piece 413, a first handle 414 and a first handle connecting piece 415. The first base 411 serves as the basic fixing part of the entire fixed clamp 41 and is installed on the back of the corresponding keel 11. The pressure head 412 is installed on the pressure head fixing piece 413 and is used to press against the rear plate of the electric trailer 6 to press or clamp the main frame 1 on the rear side of the electric trailer 6. The pressure head fixing part 413 is used to connect the first base 411 and the pressure head 412, and plays the role of supporting and transmitting force. One end of the pressure head fixing part 413 is hinged to the first base 411 at the first hinge point 416 to control the rotation of the pressure head 412 around the first base 411. The first handle 414 serves as the operating end. It is hinged to the first base 411 at the second hinge point 417 to control the rotation of the first handle 414 around the first base 411. The first handle connecting part 415 is used to connect the first handle 414 and the pressure head fixing part 413 to form a linkage structure. One end of the pressure head fixing part 413 is hinged to the first handle 414 at the third hinge point 418 to drive the first handle connecting part 415 to move through the first handle 414. The other end of the first handle connecting part 415 is hinged to the pressure head fixing part 413 at the fourth hinge point 419, thereby converting the movement of the first handle 414 into movement of the pressure head 412.

[0051] The fixed clamp 41 of this embodiment is a four-link mechanism. By operating the first handle 414, the pressure head 412 can be driven to move, thereby achieving the clamping and locking of the main frame 1 (such as Figure 2 Based on the above structure, the fixed clamp 41 of this embodiment has two working states: when the main frame 1 is fixed to the rear side of the electric trailer 6, the fixed clamp 41 is in a clamping state. At this time, the angle between the first handle 414 and the pressure head fixing part 413 is a right angle, and the second hinge point 417, the third hinge point 418 and the fourth hinge point 419 are collinear, so that the fixed clamp 41 is in a self-locking state. That is, when the three points are collinear, the first handle 414 cannot be easily moved, and the fixed clamp 41 is in a self-locking state. The clamp 41 maintains a stable clamping state to prevent it from being accidentally loosened; when the main frame 1 is unfixed from the rear side of the electric trailer 6, the fixed clamp 41 is in a released state, the angle between the first handle 414 and the pressure head fixing part 413 is an acute angle, and the second hinge point 417, the third hinge point 418 and the fourth hinge point 419 are not collinear. At this time, the fixed clamp 41 is out of the self-locking state, and the operator can easily pull the first handle 414 to lift the pressure head 412, thereby releasing the main frame 1.

[0052] like Figures 5 to 8As shown, the first telescopic rod 12 includes a first inner tube 121, a first outer tube 122 and a first connecting member 123. The first inner tube 121 has a plurality of first through holes spaced apart along its length direction, and the first outer tube 122 has a plurality of second through holes 1221 spaced apart along its length direction. One end of the first outer tube 122 is connected to the keel 11 at the top, and the other end of the first outer tube 122 is movably sleeved on the outer peripheral side of the first inner tube 121. The end of the first inner tube 121 away from the first outer tube 122 is connected to the keel 11 at the bottom, and the first connecting member 123 can be inserted into the corresponding first through hole and the corresponding second through hole 1221 to connect the first outer tube 122 and the first inner tube 121.

[0053] Based on the above structure, when the length of the first telescopic rod 12 needs to be adjusted, the first outer tube 122 can be slid relative to the first inner tube 121 to align the first through-hole at the corresponding length with the second through-hole 1221, and then the first connector 123 can be inserted to lock the current length. This embodiment achieves multi-level, adjustable height control, allowing the operator to adjust the overall height of the adjustable automatic cleaning mop based on the height of the rear side of the electric trolley 6 and the actual height of the floor being cleaned. This allows the operator to adapt to the height of the rear panel of different electric trolleys 6. Adjustment enables the four fixed clamps 41 to clamp onto the upper and lower edges of any rear panel of any electric trolley 6 (i.e., rear panels of different heights), thereby enhancing the versatility and adaptability of the adjustable automatic cleaning mop. Furthermore, when the first connector 123 is inserted into the corresponding first and second through-holes 1221, it effectively prevents the first telescopic rod 12 from accidentally sliding or deforming during use, ensuring the stability and safety of the overall structure.

[0054] It should be noted that the first inner tube 121 and the first outer tube 122 of this embodiment are made of square or round tubes, which reduces manufacturing costs. If the modular structure of the first telescopic tube is damaged, only the damaged part (e.g., a damaged tube) needs to be disassembled and replaced, without replacing the entire first telescopic rod 12. When not in use, the telescopic rod can be retracted to save space and facilitate transportation and storage. Furthermore, the first inner tube 121 and the first outer tube 122 of this embodiment are secured to the corresponding keel 11 by welding, bolts, snaps, or other means.

[0055] In some embodiments, the first connecting member 123 may be a latch that is sequentially inserted into the corresponding first and second through-holes 1221 to connect the first outer tube 122 to the first inner tube 121. Specifically, when the first outer tube 122 is inserted over the first inner tube 121, the through-holes (the first and second through-holes 1221) on the two tubes align. Inserting the latch into the aligned first and second through-holes 1221 secures the first outer tube 122 and first inner tube 121 relative to each other, preventing the length of the first telescopic rod 12 from changing due to vibration or pressure during use. To adjust the height, simply remove the latch, slide the first outer tube 122 or first inner tube 121 to the desired position, and reinsert it. For cleaning, replacement, or transport, the first inner tube 121 and first outer tube 122 can be quickly disassembled by simply removing the latch, enhancing the flexibility and convenience of the first telescopic rod 12 and simplifying operation. Compared with friction or other non-rigid connection methods, the latch structure can provide stronger mechanical locking force, ensuring that the cleaning equipment will not accidentally retract or shake during operation.

[0056] In some embodiments, the first connecting member 123 may also be a pressing piece, which is located inside the first inner tube 121 to connect the first outer tube 122 and the first inner tube 121 .

[0057] like Figure 9 As shown, the pressing piece includes a connecting portion 1231, an extension portion 1232, a mounting portion 1233, a first limiting portion 1234 and a plug-in portion 1235. The connecting portion 1231 is the central part of the entire pressing piece, and its two ends are respectively connected to an extension portion 1232, and the distance between the two extension portions 1232 gradually increases in the direction away from the connecting portion 1231, so that the two extension portions 1232 are V-shaped or fan-shaped, which helps to generate outward tension so that the plug-in portion 1235 can be better inserted into the hole. The end of the extension portion 1232 away from the connecting portion 1231 is connected to the mounting portion 1233, and the two mounting portions 1233 are arranged in parallel. The plug-in portion 1235 is connected to the mounting portion 1235. The outer wall of the part 1233 is connected, and the plug-in part 1235 is installed in the first through hole at one end away from the mounting part 1233, and the inner wall of the mounting part 1233 at one end away from the extension part 1232 is connected to the first limiting part 1234, and the first limiting part 1234 is arranged parallel to the corresponding extension part 1232. When the plug-in part 1235 is inserted into the second through hole 1221, the first inner tube 121 is connected to the first outer tube 122, and there is a gap between the two first limiting parts 1234 at one end away from the mounting part 1233, so as to ensure that the pressing piece has a certain elastic deformation space; when the plug-in part 1235 is disconnected from the second through hole 1221, the length of the first telescopic rod 12 can be movably adjusted.

[0058] The pressing piece of this embodiment is first installed in the first inner tube 121, and the plug-in parts 1235 on both sides thereof are respectively plugged into the corresponding first through holes. Based on the above structure, the pressing piece of this embodiment has two states: when the plug-in part 1235 is inserted into the second through hole 1221, it is in an unfolded and locked state. The plug-in part 1235 is inserted into the corresponding second through hole 1221. At this time, the elasticity of the extension part 1232 causes it to expand outward, forming a snap-fit ​​effect, and the first inner tube 121 and the first outer tube 122 are relatively fixed and cannot slide. When the plug-in part 1235 is disconnected from the second through hole 1221, it is in a compressed state. By pressing the plug-in part 1235 and compressing the extension part 1232 inward, the plug-in part 1235 is disconnected from the second through hole 1221. At this time, the first inner tube 121 and the first outer tube 122 can be freely moved along the length direction, thereby adjusting the length of the first telescopic rod 12. It can be understood that due to the setting of the first limiting portion 1234, when pressing the plug-in portion 1235, if the pressing force is too large, the relative abutment of the first limiting portion 1234 can prevent the plug-in portion 1235 from compressing the extension portion 1232 inward, thereby preventing the plug-in portion 1235 from detaching from the first through hole.

[0059] like Figure 5 、 Figure 10 and Figure 11 As shown, the second telescopic rod 22 includes a second inner tube 221, a second outer tube 222 and a second connecting member. The second inner tube 221 has a plurality of third through holes spaced apart along its length, and the second outer tube 222 has a plurality of fourth through holes 2221 spaced apart along its length. One end of the second outer tube 222 is clamped with the mounting beam 21, and the other end of the second outer tube 222 passes through the mounting beam 21 and the connecting beam 13 in sequence and is movably sleeved on the outer circumference of the second inner tube 221. The second outer tube 222 has a certain degree of sliding freedom; the end of the second inner tube 221 away from the second outer tube 222 is connected to the bottom frame assembly 23, and the second connecting member can be inserted into the corresponding third through hole and the corresponding fourth through hole 2221 to connect the second outer tube 222 and the second inner tube 221.

[0060] Based on the above structure, when the height of the base frame assembly 23 (i.e., the mop 3) needs to be adjusted, the total length of the telescopic rod can be changed by sliding the first outer tube 122 relative to the first inner tube 121, aligning the first through-hole at the corresponding length with the second through-hole 1221, and then inserting the first connector 123 to lock the current length. This embodiment utilizes a multi-position locking structure, allowing the operator to adjust the height of the base frame assembly 23 based on the height of the rear side of the electric trolley 6 and the actual height of the floor being cleaned, adapting to the height of the rear panels of different electric trolleys 6. Furthermore, this locking method ensures that the base frame assembly 23 does not accidentally shift due to vibration or force during cleaning, helping to maintain good contact between the mop 3 and the floor, thereby improving cleaning effectiveness. It should be noted that the second inner tube 221 and the second outer tube 222 of this embodiment are made of square or round tubes, which reduces manufacturing costs. In the event of damage to the modular structure of the second telescopic rod, only the damaged component (e.g., a damaged tube) needs to be disassembled and replaced, without having to replace the entire second telescopic rod 22. When not in use, the telescopic rod can be retracted to save space and facilitate transportation and storage. In addition, the first inner tube 121 of this embodiment is installed on the bottom frame assembly 23 by welding, bolts, snaps or other methods.

[0061] It should be noted that the first connecting member 123 and the second connecting member have the same structure. Not only can they be used interchangeably, which reduces the types of spare parts and maintenance costs, but it is also conducive to standardized production and subsequent maintenance of the equipment.

[0062] Furthermore, the sub-frame 2 also includes a first fixing member 24, a second fixing member 25 and a spring member 26. The first fixing member 24 and the second fixing member 25 are installed at one end of the second telescopic rod 22 away from the bottom frame assembly 23, and the mounting beam 21 is located between the first fixing member 24 and the second fixing member 25. That is, the first fixing member 24 is fixed to the top of the second telescopic rod 22, and the second fixing member 25 is fixed to the middle of the second telescopic rod 22. It cooperates with the first fixing member 24 to play a limiting role and prevent the second telescopic rod 22 from separating from the mounting beam 21; the spring member 26 is sleeved on the outer peripheral side of the second telescopic rod 22, and one end of the spring member 26 abuts against the side of the mounting beam 21 away from the first fixing member 24, and the other end of the spring member 26 abuts against the second fixing member 25. When the mop 3 touches the ground, the spring member 26 is compressed, generating a downward elastic force, which is transmitted to the mop 3 through the bottom frame assembly 23, so that it always sticks to the ground. Even if the ground is uneven, the spring member 26 can adapt to height changes and maintain constant pressure.

[0063] In this embodiment, the first fixing member 24, the second fixing member 25, and the spring member 26 are all mounted on the end of the second outer tube 222 of the second telescopic rod 22 that is distal from the base frame assembly 23 (i.e., the side closest to the mounting beam 21). The preload of the spring member 26 causes the mop 3 to exert a certain elastic pressure on the ground. This elastic preload ensures that the mop 3 maintains close contact with the ground, preventing it from becoming suspended even on uneven surfaces, thereby improving cleaning effectiveness. During bumpy rides or uphill and downhill conditions, the spring member 26 cushions impact forces, reducing mechanical damage to the electric tractor 6 and the cleaning device, thereby extending the service life of the equipment.

[0064] It should be noted that the first fixing member 24 and the second fixing member 25 of this embodiment are nuts.

[0065] Furthermore, the bottom frame assembly 23 includes a connecting frame 231, a connecting rod 232, a support rod 233 and a supporting diagonal beam 234. The connecting frame 231 serves as the main body of the bottom frame and is used to install the mop 3 and connect other supporting structures. The connecting rod 232 is located in the connecting frame 231, and the connecting rod 232 is arranged parallel to the mounting beam 21, playing a lateral support role. One end of the connecting rod 232 is connected to the inner wall of one side of the connecting frame 231, and the other end passes through the two second telescopic rods 22 in sequence and is connected to the inner wall of the other side of the connecting frame 231, so as to enhance the overall rigidity of the connecting frame 231 while also serving as a structural connection point. The support rod 233 is located between the two second telescopic rods 22, bearing the supporting force in the vertical direction. One end of the support rod 233 is inserted into the connecting beam 13 to form a stable fulcrum, and one end of the support rod 233 can be installed in the connecting beam 13 by insertion, and the other end of the support rod 233 is respectively connected to one end of the two supporting oblique beams 234, and the other end of the supporting oblique beam 234 is connected to the connecting frame 231. The distance between the two supporting oblique beams 234 gradually increases in the direction away from the support rod 233, forming a triangular structure, which plays a role of central stability and balance, can effectively disperse the load, enhance the structure's anti-deformation ability, and improve the bending strength and overall stability.

[0066] The mop 3 and the bottom frame assembly 23 of this embodiment have a chimeric structure, which facilitates their disassembly and installation. The mop 3 can be removed from the bottom frame assembly 23, cleaned, and then reinstalled. In addition, the bottom frame assembly 23 of this embodiment can also be disassembled and assembled from the second outer tube 222 by disassembling the second inner tube 221 and the second outer tube 222. It should be noted that the connecting frame 231, connecting rod 232, support rod 233, and supporting inclined beam 234 of this embodiment are made of square tubes or round tubes, which are low in manufacturing cost.

[0067] like Figure 14 and Figure 15As shown, the adjustment assembly 5 includes two telescopic clamps 51 , which are fixedly mounted at the front end of the main frame 1 , and the movable downward pressing portion of the telescopic clamp 51 is connected to the corresponding position of the mounting beam 21 of the sub-frame 2 .

[0068] Specifically, the telescopic clamp 51 includes a second handle 511, a second handle connector 512, a second base 513 and a clamp rod 514. The second base 513 serves as the support base of the entire telescopic clamp 51 and is installed at both ends of the keel 11 at the top. The second base 513 has a hinge portion 5131 and a hollow second limiting portion 5132 on the side away from the keel 11. The second handle 511 serves as the operating end for manual operation by the operator. It has a right-angle portion 5111 and a handle portion 5132 connected to the right-angle portion 5111. 112, forming an L-shaped structure; one end of the right-angle portion 5111 away from the handle portion 5112 is hinged to the hinge portion 5131 at the fifth hinge point 515, and the right angle of the right-angle portion 5111 is hinged to one end of the second handle connecting member 512 at the sixth hinge point 516. The second handle connecting member 512 serves as an intermediate component connecting the second handle 511 and the clamping rod 514, and the other end thereof is hinged to one end of the clamping rod 514 at the seventh hinge point 517. The other end of the clamping rod 514 passes through the second limiting portion 5132 and is connected to the corresponding end of the mounting beam 21.

[0069] In this embodiment, the telescopic action of the clamp rod 514 is achieved by the linkage between the hinge points, so that the operator can drive the clamp rod 514 to extend and retract by operating the second handle 511, thereby changing the height position of the bottom frame assembly 23. The working state of the telescopic clamp 51 is divided into two types: when the bottom frame assembly 23 is driven to rise and fall (such as Figure 2 The direction of rotation shown is upward), the fifth hinge point 515, the sixth hinge point 516 and the seventh hinge point 517 are not collinear, and the telescopic clamp 51 is in a non-dead point state, and can perform normal transmission and motion output; when the bottom frame assembly 23 reaches the specified position, the fifth hinge point 515, the sixth hinge point 516 and the seventh hinge point 517 are collinear, and the second handle connecting member 512 and the clamp rod 514 form a straight line, and the telescopic clamp 51 enters the dead point state. In this state, the telescopic clamp 51 has a certain self-locking characteristic to maintain the bottom frame assembly 23 in a specified high-position locking state, which can prevent the bottom frame assembly 23 from accidentally falling or rising without external force, thereby improving safety.

[0070] In summary, the embodiment of the present invention provides an adjustable automatic cleaning mop, which can be installed on an existing electric trailer for power dragging. One person riding the electric trailer can mop a large area of ​​the ground in a short time, which is more efficient than manual cleaning. The adjustable automatic cleaning mop is easy to assemble and disassemble and easy to clean.
