Description

Technical Field

[0001] This utility model relates to the field of building site cleaning technology, and in particular to a modular automatic cleaning device. Background Technology

[0002] In current indoor floor cleaning practices, traditional methods primarily rely on manual mopping. For small areas, this method can maintain a certain level of cleaning efficiency. However, when faced with large-area floor cleaning tasks such as workshops or large venues, it often requires more manpower and time, and may even necessitate the use of multiple mops simultaneously to increase cleaning speed, increasing labor intensity and costs, resulting in overall low cleaning efficiency.

[0003] Besides traditional manual cleaning methods, there are also large-scale mechanical devices on the market specifically designed for cleaning large areas, such as sweepers and sprinklers. While these devices can improve cleaning efficiency to some extent, they generally have some limitations. First, these devices are usually designed as a single, large, and complex structure, significantly increasing their manufacturing costs. Second, due to their fixed structural design, large size, and integrated design, they are only suitable for a single scenario, lacking versatility. Utility Model Content

[0004] The technical problem this utility model aims to solve is that when cleaning indoor floors with large areas, such as workshops or venues, the current practice is to mop the floor manually, which is time-consuming, labor-intensive, and has low cleaning efficiency, or to use large equipment for cleaning, which is expensive and has poor versatility.

[0005] To address the aforementioned technical problems, this utility model provides an assembled automatic cleaning device, comprising a main frame, a sub-frame, a cleaning head, and mounting components.

[0006] The main frame includes a first mounting frame and a first connecting frame. The first mounting frame includes two first connecting beams and two first support columns. The two first support columns are spaced apart between the two first connecting beams, and the two ends of the first support columns are respectively connected to the two first connecting beams. The two ends of the first connecting beams are respectively provided with a mounting component for detachable connection to the rear side of the electric trailer. The first mounting frame is connected to the first connecting beams or the first support columns.

[0007] The sub-frame includes a second connecting frame and a second mounting frame. The second connecting frame includes two sleeves, which are spaced apart horizontally. The second mounting frame includes a second support column and a bottom frame assembly. The two second support columns are spaced apart horizontally and mounted on the bottom frame assembly. One end of each sleeve passes through the first connecting frame and is detachably connected to the corresponding second support column. The cleaning head is detachably mounted on the second mounting frame.

[0008] In some embodiments, the first connecting beam and the first supporting column form a clearance on the side away from the second connecting frame.

[0009] In some embodiments, the first connecting frame includes a second connecting beam, a third connecting beam, and a fourth connecting beam. The second connecting beam is installed at the bottom of the first connecting beam located at the bottom. The third connecting beam and the fourth connecting beam are spaced apart in a vertical direction. The third connecting beam is connected to the first connecting beam or the first support column, and the fourth connecting beam is connected to the second connecting beam.

[0010] In some embodiments, the second connecting frame further includes a spring and a locking member. The side wall of the sleeve has two sets of connecting holes spaced apart along its length. Each set of connecting holes has at least two threaded holes spaced apart around the axis of the sleeve. The locking member is screwed to the threaded holes. The third connecting beam is located between the two sets of connecting holes. The spring is sleeved on the outer periphery of the sleeve, and one end of the spring abuts against the third connecting beam, while the other end abuts against the locking member screwed onto the connecting hole set near the second mounting frame.

[0011] In some embodiments, the second mounting frame further includes a support component located between two second support columns, with one end mounted on the bottom frame component and the other end insertable into the fourth connecting beam.

[0012] In some embodiments, the support assembly includes a third support column and two support beams. One end of the third support column passes through the first connecting frame and is connected to one end of each of the two support beams. The other end of each support beam is connected to the bottom frame assembly, and the distance between the two support beams gradually increases in the direction closer to the bottom frame assembly.

[0013] In some embodiments, the bottom frame assembly includes a connecting rod and a connecting frame, the connecting rod is disposed within the connecting frame and both ends of the connecting rod are respectively connected to the connecting frame, the second support column is connected to the connecting rod, and one end of the support assembly is connected to the connecting frame.

[0014] In some embodiments, the connecting frame is ring-shaped or rectangular.

[0015] In some embodiments, the mounting element is a push-pull clamp.

[0016] In some embodiments, the cleaning head includes a mop, broom head, vacuum cleaner head, or spray nozzle.

[0017] Compared with the prior art, the advantages of the assembled automatic cleaning device of this utility model are as follows:

[0018] The first mounting frame of this utility model's modular automatic cleaning device has mounting brackets at both ends, allowing for quick connection to the rear of an electric trailer. The electric trailer propels the device forward, enabling mobile cleaning operations. During movement, the cleaning head performs sweeping, vacuuming, or wet mopping. After the task is completed, the modular automatic cleaning device can be quickly detached using the mounting brackets. This modular automatic cleaning device is adaptable to existing electric trailers for use in various scenarios, offering strong versatility. Furthermore, only one person riding the electric trailer is needed to clean a large area of ​​ground in a very short time, resulting in high cleaning efficiency.

[0019] Furthermore, the entire modular automatic cleaning device consists of multiple modules, including a main frame, a sub-frame, and cleaning heads.

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] like Figures 1 to 6 As shown, this utility model provides an assembled automatic cleaning device, including a main frame 1, a sub-frame 2, a cleaning head 3, and mounting parts 4. The main frame 1 serves as the basic skeleton of the entire assembled automatic cleaning device, and includes a first mounting frame 11 and a first connecting frame 12. The first mounting frame 11 includes two first connecting beams 111 and two first support columns 112. The two first connecting beams 111 serve as the main beams in the horizontal direction, forming the main load-bearing structure of the main frame 1. A mounting part 4 is provided at each end of the first connecting beam 111 for detachable connection to the rear side of the electric trailer 5. The mounting part 4 is fixed to the first connecting beam 111 by bolts, clips, or other means to ensure that the assembled automatic cleaning device can be firmly connected to the rear side of the electric trailer 5.

[0030] In this embodiment, two first support columns 112 are spaced apart between two first connecting beams 111, and both ends of the first support columns 112 are connected to the two first connecting beams 111 respectively. The first support columns 112 provide vertical support for the first connecting beams 111, thereby enhancing the rigidity of the first mounting frame 11 and improving its bending resistance, making the entire structure more stable. The first connecting frame 12 is connected to the first connecting beams 111 or the first support columns 112.

[0031] The secondary frame 2 is used to install the cleaning head 3. It includes a second connecting frame 21 and a second mounting frame 22. The second connecting frame 21 includes two sleeves 211, which are spaced apart in the horizontal direction. The second mounting frame 22 includes a second support column 221 and a bottom frame assembly 222. The two second support columns 221 are spaced apart in the horizontal direction and are installed on the bottom frame assembly 222. One end of the sleeve 211 passes through the first connecting frame 12 and is detachably connected to the corresponding second support column 221. Each second support column 221 is inserted into a corresponding sleeve 211. After insertion, it is detachably fixed by means of pins, bolts, quick clips, etc., so that the second connecting frame 21 and the second mounting frame 22 can be quickly installed or disassembled, which is convenient for transportation, maintenance or replacement of different types of cleaning heads 3. The cleaning head 3 can be detachably installed on the second mounting frame 22 to realize the functions of sweeping, washing or vacuuming the ground.

[0032] Based on the above structure, the first mounting frame 11 of the assembled automatic cleaning device has mounting parts 4 at both ends, which can be quickly connected to the rear of the electric trailer 5. The electric trailer propels the device forward to achieve mobile cleaning operations. During movement, the cleaning head 3 performs sweeping, vacuuming, or wet mopping operations. After the task is completed, the assembled automatic cleaning device can be quickly detached via the mounting parts 4. This assembled automatic cleaning device can be adapted to existing electric trailers 5 for installation, allowing for use in different scenarios. It is highly versatile, and only one person needs to ride the electric trailer 5 to clean a large area of ​​ground in a very short time, resulting in high cleaning efficiency.

[0033] Furthermore, the entire modular automatic cleaning device consists of multiple modules, including the main frame 1, the sub-frame 2, and the cleaning head 3. The mounting component 4 is detachably connected to the electric trailer 5, and the sleeve 211 is detachably connected to the second support column 221. This not only avoids the manufacturing difficulties and material waste associated with an integrated structure but also facilitates easy assembly and disassembly, as well as maintenance, cleaning, and replacement. Simultaneously, all components, such as the first connecting beam 111, the first support column 112, the sleeve 211, and the second support column 221, can be produced and managed in a standardized manner, reducing overall manufacturing costs.

[0034] It should be noted that the cleaning device in this embodiment has a simple structure and is particularly suitable for workshops, stadiums and other places with large areas of ground that can accommodate the riding of electric trailers.

[0035] like Figure 5 As shown, the first connecting beam 111 and the first support column 112 form a clearance 113 on the side away from the second connecting frame 21, so as to leave a recessed or gap area on this side to adapt to the rear structure of the electric trailer 5, avoid collision or interference during installation, improve the versatility of the first mounting frame 11, and enable it to adapt to various models of electric trailers 5.

[0036] Understandably, in this embodiment, the first support column 112 and the first connecting beam 111 form a rectangular structure, which can effectively disperse the vibration and impact force generated during the operation of the electric trailer 5, preventing structural deformation or loosening. Preferably, the two first support columns 112 are arranged in parallel, the two first connecting beams 111 are arranged in parallel, and the first connecting beams 111 are arranged perpendicular to the first support columns 112. The first connecting beams 111 and the first support columns 112 are square tubes, which are welded together to form the first mounting frame 11, resulting in low manufacturing costs.

[0037] In some embodiments, the first connecting frame 12 includes a second connecting beam 121, a third connecting beam 122, and a fourth connecting beam 123. The second connecting beam 121 is installed at the bottom of the first connecting beam 111 located at the bottom, serving as the connecting base for the fourth connecting beam 123. The third connecting beam 122 and the fourth connecting beam 123 are spaced apart in a vertical direction. The third connecting beam 122 is connected to the first connecting beam 111 or the first support column 112, and the fourth connecting beam 123 is connected to the second connecting beam 121. Understandably, in this embodiment, the third connecting beam 122 is located at the top or middle of the first mounting frame 11 and is connected to the first connecting beam 111 or the first support column 112.

[0038] It should be noted that, in this embodiment, the third connecting beam 122 can be connected to the first connecting beam 111 or the first support column 112 by welding, threaded connection, or other connection methods. The fourth connecting beam 123 can be connected to the second connecting beam 121 by welding, threaded connection, or other connection methods. The second connecting beam 121 is a square tube, which is welded to the first connecting beam 111 located at the bottom. The third connecting beam 122 and the fourth connecting beam 123 are also square tubes.

[0039] Understandably, the third connecting beam 122 in this embodiment can also be detachably connected to the first connecting beam 111 via a telescopic push-pull clamp, with one end of the telescopic push-pull clamp connected to the first connecting beam 111 and the other end connected to the third connecting beam 122.

[0040] like Figure 2 and Figure 6 As shown, the second connecting frame 21 also includes a spring member 212 and a locking member 213. The side wall of the sleeve 211 has two sets of connecting holes spaced apart along its length. Each set of connecting holes has at least two threaded holes spaced apart around the axis of the sleeve 211. The locking member 213 is screwed into the threaded holes. One end of the sleeve 211 passes through the third connecting beam 122 and the fourth connecting beam 123 in sequence and connects to the corresponding second support column 221. The third connecting beam 122 is located between the two sets of connecting holes. The spring member 212 is sleeved on the outer periphery of the sleeve 211, with one end abutting against the third connecting beam 122 and the other end abutting against the locking member 213 screwed onto the connecting hole set near the second support column 221. This ensures a stable connection between the sub-frame 2 and the main frame 1. Simultaneously, the spring member 212 provides an elastic preload when the cleaning head 3 contacts the ground. The second connecting frame 21 in this embodiment adopts a double-column structure, which is more stable and can withstand greater lateral and torsional forces. Among them, sleeve 211 is a round tube.

[0041] In some embodiments, the second mounting frame 22 further includes a support component 223, which is located between two second support columns 221. One end of the support component 223 is mounted on the bottom frame component 222, and the other end can be inserted into the fourth connecting beam 123. While enhancing the structural strength, the support component 223 also provides auxiliary support.

[0042] In some embodiments, the support assembly 223 includes a third support column 2231 and two support inclined beams 2232. One end of the third support column 2231 passes through the first connecting frame 12 and connects to one end of each of the two support inclined beams 2232. The other end of each support inclined beam 2232 is connected to the bottom frame assembly 222. The distance between the two support inclined beams 2232 gradually increases towards the bottom frame assembly 222, i.e., the distance between the tops of the two support inclined beams 2232 is narrower, and the distance between the bottoms of the two support inclined beams 2232 is wider, forming a "V" shape structure. This outward-expanding arrangement of the support inclined beams 2232 effectively enhances their auxiliary support and balance capabilities. Furthermore, the third support column 2231, acting as a central axis, can evenly distribute the contact pressure to both sides through the support inclined beams 2232, making the cleaning head 3 on the bottom frame assembly 222 experience more balanced force during operation, reducing local stress concentration, and preventing structural deformation or damage due to unilateral force. The third support column 2231 is a circular tube.

[0043] In some embodiments, the bottom frame assembly 222 includes a connecting rod 2221 and a connecting frame 2222. The connecting rod 2221 is disposed within the connecting frame 2222, and both ends of the connecting rod 2221 are connected to the connecting frame 2222. The connecting rod 2221 serves as a structural reinforcement, and a second support column 221 is connected to it, allowing the sleeve 211 to be connected to the entire bottom frame assembly 222 via the second support column 221, thereby enhancing the stability of the bottom frame assembly 222. One end of the support assembly 223 is connected to the connecting frame 2222, thus enhancing the overall structural rigidity. The connecting rod 2221 is a circular tube.

[0044] Understandably, the two supporting diagonal beams 2232 are connected to the connecting frame 2222, and the connecting rod 2221 runs through the interior of the connecting frame 2222, forming a truss-like structure, which can effectively prevent the connecting frame 2222 from bending or deforming due to force.

[0045] In some embodiments, the connecting frame 2222 is annular or rectangular in shape. The annular connecting frame 2222 is a closed circle or ellipse, which can provide a uniform force distribution; the rectangular connecting frame 2222 is a rectangular or approximately square structure, which is simple in structure and easy to process and install.

[0046] In some embodiments, the mounting component 4 is a push-pull clamp 41, with multiple push-pull clamps 41 distributed around the first mounting frame 11. This allows for quick connection and disconnection between the assembled automatic cleaning device and the electric trailer 5. By pulling the push-pull clamps 41, the assembled automatic cleaning device is quickly fixed to the rear side of the electric trailer 5 (e.g., ...). Figure 1 and Figure 2 (as shown); push the push-pull clamp 41 to quickly separate the assembled automatic cleaning device (as shown). Figure 3 As shown in the diagram, compared to the traditional bolt fixing method, this method improves installation efficiency and reduces manual operation time. In addition, the push-pull clamp 41 has a self-locking structure, which makes it difficult to loosen after clamping, and can effectively prevent the device from shaking or falling off during the movement of the cleaning device by the electric trailer 5.

[0047] In some embodiments, the cleaning head 3 includes a mop, a broom head, a vacuum cleaner head, or a spray nozzle.

[0048] In this embodiment, the mop is mainly used for wet cleaning. It is installed in the connecting frame 2222 and is suitable for removing stains, dust, and liquid residue from the floor. It dissolves and removes dirt through wetting, achieving a better cleaning effect. The broom head is used for dry cleaning. It is installed in the connecting frame 2222 and is used to clean large particles of debris, dust, and other loose materials from the floor. The vacuum head can be installed in the connecting frame 2222 via a mounting plate. A vacuum suction device is placed on the electric trailer 5 and connected to the vacuum head via a pipe to generate strong suction to collect dust, debris, and other small particulate contaminants. The spray nozzle can be installed in the connecting frame 2222 via a mounting plate. A cleaning can containing detergent is placed on the electric trailer 5 and connected to the spray nozzle via a pipe to evenly spray the cleaning solution onto the floor, helping to break down stains and facilitating subsequent wiping or rinsing.

[0049] In summary, this utility model embodiment provides an assembled automatic cleaning device. Its first mounting frame 11 has mounting parts 4 at both ends that can be quickly connected to the rear of an electric trailer 5. The electric trailer drives the device forward to perform mobile cleaning operations. The cleaning head 3 performs sweeping, vacuuming, or wet mopping operations during movement. After the task is completed, the assembled automatic cleaning device can be quickly detached via the mounting parts 4. This assembled automatic cleaning device can be adapted to existing electric trailers 5 for use in different scenarios, offering strong versatility. Only one person needs to ride the electric trailer 5 to clean a large area of ​​ground in a very short time, making it more efficient than manual cleaning. Furthermore, the entire assembled automatic cleaning device consists of multiple modules, including a main frame 1, a secondary frame 2, and a cleaning head 3. The mounting parts 4 are detachably connected to the electric trailer 5, and the sleeve 211 is detachably connected to the second support column 221. This not only avoids the manufacturing difficulties and material waste associated with an integrated structure but also facilitates easy assembly and disassembly, maintenance, cleaning, or replacement. Meanwhile, all components, such as the first connecting beam 111, the first support column 112, the sleeve 211, and the second support column 221, can be produced in a standardized manner (e.g., made of square and round tubes) and managed in inventory, which reduces the overall manufacturing cost.

[0050] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
