Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, specifically providing a floating cover installation structure and a floor cleaning device. Background Technology

[0002] Robotic vacuum cleaners, which have emerged in recent years as floor cleaning devices, are increasingly favored by home users. To achieve better cleaning results, some manufacturers adopt a floating design for the central cleaning component at the bottom of the robotic vacuum cleaner. This allows the cover of the central cleaning component to always be in contact with the ground. When encountering uneven ground, it can float up and down within the designed stroke, which can not only avoid bumping into protrusions on the ground, but also increase the degree of contact in carpet and other scenarios.

[0003] There are two main types of floating designs for existing center sweeping components. One type involves mounting a cover plate on the center sweeping component, which floats with the entire component and relies on its own weight to maintain contact with the ground. The applicant's research has revealed that this solution suffers from structural complexity, high cost, and difficult assembly.

[0004] Accordingly, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] This application aims to solve at least one of the above-mentioned technical problems, namely, to address the issues of complex structure, high cost, and difficult assembly of the floating sweeping components in existing robotic vacuum cleaners.

[0006] In a first aspect, this application provides a floating cover plate mounting structure, comprising: a housing, wherein a mounting groove and a receiving groove are formed at the bottom of the housing, the mounting groove is configured to mount a roller brush, a first snap-fit ​​structure is formed on the groove wall of the receiving groove, and a floating space is formed between the first snap-fit ​​structure and the bottom of the receiving groove; a cover plate, comprising a main body and a second snap-fit ​​structure disposed on the main body, the main body having a clearance hole configured to allow a portion of the roller brush to extend out, the main body being pivotally connected to the mounting groove on a first side along a first direction, the second snap-fit ​​structure being disposed on a second side of the main body along the first direction and configured to engage with the first snap-fit ​​structure; a scraper, the scraper being fixedly mounted on the main body; and an elastic member, the elastic member being disposed at the bottom of the housing and elastically abutting against the cover plate, such that the cover plate can float up and down within a stroke defined by the floating space.

[0007] By adopting the above technical solution, this application can reduce the structural complexity of the floating cover, lower costs, and simplify assembly. Specifically, by forming a receiving groove at the bottom of the housing and setting a first snap-fit ​​structure within the receiving groove, and setting a second snap-fit ​​structure on the main body of the cover, not only is it beneficial for the rapid installation and disassembly of the cover, but the structure of the cover is also simplified, reducing manufacturing costs. The elastic element is located at the bottom of the housing and elastically abuts against the cover. In addition to enabling the cover to float up and down, it can further reduce assembly difficulty, allowing both the cover and the elastic element to be assembled and disassembled at the bottom of the housing without disassembling the housing, thus accelerating production and maintenance efficiency.

[0008] In the preferred embodiment of the above-mentioned floating cover plate installation structure, the side edge of the second side of the main body extends outward to form an elastic support arm, and the second snap-fit ​​structure is disposed on the elastic support arm.

[0009] By setting up elastic support arms, the elastic deformation of the support arms can be used to achieve quick installation and removal of the cover plate, reducing the difficulty of installation and removal and improving the efficiency of installation and removal.

[0010] In the preferred embodiment of the above-mentioned floating cover plate installation structure, the elastic support arm is V-shaped and includes a first arm segment and a second arm segment. One end of the first arm segment is connected to the main body, the second end of the first arm segment is connected to the first end of the second arm segment, the second end of the second arm segment is a free end, and the second snap-fit ​​structure is provided in the second arm segment.

[0011] In the preferred embodiment of the above-mentioned floating cover plate installation structure, the first snap-fit ​​structure is a transverse rib, and the second snap-fit ​​structure is a snap-fit ​​protrusion; or one of the first snap-fit ​​structure and the second snap-fit ​​structure is a slot or hole, and the other is a snap-fit ​​protrusion.

[0012] In the preferred embodiment of the above-mentioned floating cover plate installation structure, the two ends of the first side of the main body extend outward along the second direction to form a rotating shaft, and the bottom of the housing forms two vertical walls on the outer sides of the two ends of the mounting groove in the length direction. Each vertical wall forms a shaft hole, and the two rotating shafts are respectively inserted into the two shaft holes, wherein at least one of the two shaft holes is an elongated hole.

[0013] By setting at least one shaft hole as an elongated hole, it is beneficial to further reduce the installation difficulty of the cover plate shaft and realize the detachable design of the cover plate.

[0014] In the preferred embodiment of the above-mentioned floating cover plate installation structure, a limiting protrusion is formed on the inner surface of the elongated hole. When the cover plate is installed, the rotating shaft located on one side of the elongated hole is restricted between the limiting protrusion and one end of the elongated hole.

[0015] By setting a limiting protrusion inside the elongated hole, the rotating shaft can be limited, preventing the cover plate from shifting due to the rotating shaft moving inside the elongated hole, thus improving the stability of the cover plate installation.

[0016] In the preferred embodiment of the above-mentioned floating cover plate installation structure, a mounting position is formed on the first side of the bottom of the housing near the main body, and the elastic member is installed in the mounting position. In the installed state, the elastic member extends from the first side of the main body and abuts against the inner surface of the first side of the main body.

[0017] In the preferred embodiment of the above-mentioned floating cover plate installation structure, the elastic element is an elastic plate, the elastic plate includes a connecting segment and an elastic segment connected to each other, the connecting segment is snapped into the installation position, and the elastic segment is at least partially inclined upward in a direction away from the connecting segment and forms a gap between itself and the bottom of the installation position.

[0018] By using elastic plates, production costs can be reduced and the design difficulty of elastic components can be decreased; by snapping the connecting section of the elastic plate into the installation position, the installation stability of the elastic plate can be improved.

[0019] In the preferred embodiment of the above-mentioned floating cover plate installation structure, the installation position includes a limiting groove and a limiting rib disposed in the limiting groove. A limiting insertion hole is formed between the limiting rib and the first end of the limiting groove in the length direction. A limiting locking rib is formed on the side of the limiting rib away from the first end of the limiting groove. The connecting section includes a first vertical section, a horizontal section, a second vertical section and a locking section connected in sequence. The first vertical section, the horizontal section and the second vertical section are combined to form an "n" shape. The locking section extends from the free end of the second vertical section toward the direction close to the first vertical section. The elastic section extends from the free end of the second vertical section away from the first vertical section. In the installed state, the first vertical section is inserted into the limiting insertion hole, and the locking section engages with the limiting locking rib.

[0020] In a second aspect, this application also provides a floor cleaning device, which includes a roller brush and a floating cover mounting structure as described in any of the above technical solutions, wherein the roller brush is installed in the mounting groove at the bottom of the housing and extends partially from the clearance hole.

[0021] The ground cleaning equipment of this application, by setting a floating cover plate installation structure at the bottom of the shell, can reduce the structural complexity of the equipment, realize the quick installation and removal of the cover plate, and reduce the production and maintenance costs of the equipment.

[0032] Preferred embodiments of this application will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Additionally, in the description of this application, "a plurality of" refers to at least two.

[0034] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0035] First refer to Figures 1 to 3 This paper provides a brief description of the floating cover plate installation structure of this application.

[0036] like Figures 1 to 3 As shown, to address the problems of complex structure, high cost, and difficult assembly of existing floating sweeping components in robotic vacuum cleaners, the floating cover plate mounting structure of this application includes a housing 1, a cover plate 2, a scraper 3, and an elastic element 4. The bottom of the housing 1 has a mounting groove 11 and a receiving groove 12. The mounting groove 11 is configured to mount the roller brush 7. A first snap-fit ​​structure 13 is formed on the groove wall of the receiving groove 12, and a floating space is formed between the first snap-fit ​​structure 13 and the bottom of the receiving groove 12. The cover plate 2 includes a main body 21 and a second snap-fit ​​structure 22 disposed on the main body 21. The main body 21 has a clearance hole 211, which is configured to allow a portion of the roller brush 7 to extend out. The main body 21 extends along a first direction (in this application, the width direction of the main body 21, i.e., the direction of the width of the main body 21). Figure 1 The first side (up and down direction) Figure 1 The main body 21 (as shown) is pivotally connected to the mounting groove 11 on its lower side, and the second snap-fit ​​structure 22 is disposed on the second side of the main body 21 along the first direction. Figure 1 The upper side of the main body 21 is shown, and it is configured to engage with the first snap-fit ​​structure 13. The scraper 3 is fixedly installed on the main body 21 and is used to scrape dust into the floor cleaning device during the cleaning process. The elastic member 4 is provided at the bottom of the housing 1 and elastically abuts against the cover plate 2, so that the cover plate 2 can float up and down within the stroke limited by the floating space.

[0037] When the floating cover plate mounting structure is applied to floor cleaning equipment, such as a robot vacuum cleaner, the first side of the main body 21 of the cover plate 2 is pivotally connected to the mounting groove 11, and the second side is engaged with the first engaging structure 13 through the second engaging structure 22. A floating space is formed in the receiving groove 12 where the first engaging structure 13 is located. Therefore, during the robot vacuum cleaner's movement, the second side of the cover plate 2 has the ability to pivot around the first side and float up and down. Under the elastic force of the elastic member 4, the cover plate 2 will always be in contact with the ground.

[0038] When it is necessary to install the cover plate 2 and the elastic element 4, simply install the elastic element 4 at the bottom of the housing 1, pivot the first side of the cover plate 2 to the mounting groove 11, and pivot the cover plate 2 in the closing direction so that the second snap-fit ​​structure 22 engages with the first snap-fit ​​structure 13. When it is necessary to remove the cover plate 2, simply separate the second snap-fit ​​structure 22 from the first snap-fit ​​structure 13 to pivotally open the cover plate 2, and perform cleaning, maintenance, replacement, or other operations on the roller brush 7.

[0039] By adopting the above technical solution, this application can reduce the structural complexity of the cover plate 2, reduce costs, and decrease assembly difficulty. Specifically, by forming a receiving groove 12 at the bottom of the housing 1 and providing a first snap-fit ​​structure 13 within the receiving groove 12, and providing a second snap-fit ​​structure 22 on the main body 21 of the cover plate 2, it is not only beneficial for the quick installation and disassembly of the cover plate 2, but also simplifies the structure of the cover plate 2 and reduces manufacturing costs. The elastic element 4 is provided at the bottom of the housing 1 and elastically abuts against the cover plate 2. In addition to enabling the cover plate 2 to float up and down, it can further reduce assembly difficulty, allowing both the cover plate 2 and the elastic element 4 to be assembled and disassembled at the bottom of the housing 1 without disassembling the housing 1, thus accelerating production and maintenance efficiency.

[0040] The following is combined with Figures 1 to 8 This application will now describe one specific implementation method.

[0041] like Figures 1 to 8 As shown, in one specific embodiment, the floating cover plate mounting structure includes a housing 1, a cover plate 2, a scraper 3, an elastic element 4, a wear-resistant element 5, and a pressure strip 6.

[0042] like Figures 1 to 3 As shown, the bottom of the housing 1 has a mounting groove 11 and a receiving groove 12. The mounting groove 11 is used to mount the roller brush 7, and a first snap-fit ​​structure 13 is formed on the inner wall of the receiving groove 12. The mounting groove 11 is generally a long, arc-shaped groove. There are two receiving grooves 12, which are respectively located on the outer sides of the two ends of the receiving groove 12 along the length direction of the mounting groove 11. Each receiving groove 12 has a first snap-fit ​​structure 13. In this embodiment, the first snap-fit ​​structure 13 is a transverse rib, that is, a rib-like structure formed by the outward protrusion of the groove wall of the receiving groove 12.

[0043] like Figure 3 As shown, the bottom of the housing 1 also has a mounting position 15 for mounting the elastic element 4. In this embodiment, the mounting position 15 is generally groove-shaped and there are two of them. The two mounting positions 15 are respectively arranged on the outer sides of both ends of the mounting groove 11 along the length direction of the mounting groove 11 to improve the floating stability of the cover plate 2 after it is installed. Each mounting position 15 is arranged side by side with the receiving groove 12 on the same side. When the cover plate 2 is installed, the mounting position 15 corresponds to the first side of the cover plate 2, and the receiving groove 12 corresponds to the second side of the cover plate 2. (Refer to...) Figure 4 and Figure 5 The mounting position 15 includes a limiting groove 151 and a limiting rib 152 disposed in the limiting groove 151. A limiting insertion hole 153 is formed between the limiting rib 152 and the first end (i.e. the end away from the receiving groove 12) in the length direction of the limiting groove 151. A limiting clamping rib 154 is formed on the side of the limiting rib 152 away from the first end of the limiting groove 151.

[0044] Reference Figure 3 and Figure 4 Two vertical walls 16 are formed on the outer sides of both ends of the mounting groove 11 at the bottom of the housing 1, and each vertical wall 16 has a shaft hole 14. Each vertical wall 16 is located on the outer side of the receiving groove 12 and the mounting position 15 on the same side, and serves to enclose and form a portion of the receiving groove 12 and the mounting position 15. Furthermore, one of the shaft holes 14 is a round hole, and the other is an elongated hole. The elongated hole reduces the difficulty of installing the rotating shaft 213 of the cover plate 2 and enables the cover plate 2 to be detachable. Furthermore, a limiting protrusion 141 is formed on the inner surface of the elongated hole, transitioning from the inner surface of the elongated hole towards the inward direction.

[0045] Reference Figure 5 , Figure 7 and Figure 8 As shown, the cover plate 2 includes a main body 21, on which a clearance hole 211 is provided. The clearance hole 211 is a rectangular hole. The two ends of the first side of the main body 21 are along the second direction (i.e., the length direction of the main body 21, that is...) Figure 1 The cover plate 2 extends outward in the left and right directions to form a rotating shaft 213. The two rotating shafts 213 are inserted into the two shaft holes 14, respectively, to achieve a pivotal connection between the cover plate 2 and the bottom of the housing 1. When the cover plate 2 is installed, the rotating shaft 213 located on one side of the elongated hole is confined between the limiting protrusion 141 and one end of the elongated hole, preventing the rotating shaft 213 from shifting within the elongated hole and causing the cover plate 2 to move, thus improving the installation stability of the cover plate 2. Furthermore, this design allows for replacement or cleaning / repair of the roller brush 7 without completely removing the cover plate 2. Simply separating the second snap-fit ​​structure 22 from the first snap-fit ​​structure 13 allows the cover plate 2 to be pivotally opened, enabling cleaning, repair, or replacement of the roller brush 7.

[0046] An elastic support arm 212 extends outward from the second side of the main body 21, and a second snap-fit ​​structure 22 is disposed on the elastic support arm 212. Corresponding to the two first snap-fit ​​structures 13, this embodiment also provides two elastic support arms 212 and two snap-fit ​​structures 22, and the first snap-fit ​​structures 13 and the second snap-fit ​​structures 22 are disposed in a one-to-one correspondence, which can improve the stability of the installation and floating of the cover plate 2. Specifically, the elastic support arm 212 is V-shaped and the two elastic support arms 212 are respectively disposed at both ends of the second side of the main body 21. Each elastic support arm 212 includes a first arm segment 2121 and a second arm segment 2122. One end of the first arm segment 2121 (i.e. Figure 8 The upper end of the first arm segment 2121 (as shown) is connected to the main body 21, and the second end of the first arm segment 2121 (i.e., the upper end of the first arm segment 2121) is connected to the main body 21. Figure 8 The lower end shown) and the first end of the second arm segment 2122 (i.e. Figure 8 The lower end of the second arm segment 2122 (as shown) is connected by an arc-shaped transition. Figure 8 The upper end shown is a free end, which extends away from the first arm segment 2121 and forms an operating protrusion 23. The operating protrusion 23 facilitates the application of force when assembling and disassembling the cover plate 2, reducing the difficulty of assembly and disassembly. Furthermore, each second arm segment 2122 is provided with a second snap-fit ​​structure 22, which is located on the side of the second arm segment 2122 away from the first arm segment 2121 and in the lower middle part of the second arm segment 2122. In this embodiment, the second snap-fit ​​structure 22 is a snap-fit ​​protrusion. When the cover plate 2 is closed, the upper side of the snap-fit ​​protrusion and the lower side of the transverse rib snap together. Thus, by providing the elastic support arm 212, the elastic deformation of the elastic support arm 212 can be used to achieve quick installation and disassembly of the cover plate 2, reducing the difficulty of assembly and disassembly and improving the efficiency of assembly and disassembly.

[0047] Continue to refer to Figure 5 , Figure 7 and Figure 8 The scraper 3 is fixedly installed on the inner side of the main body 21 and partially extends out of the clearance hole 211. Specifically, a plurality of connecting holes 214 are spaced apart along the second direction (i.e., the length direction of the main body 21) on the inclined surface formed on the second side of the main body 21. A plurality of through holes 31 are spaced apart on the scraper 3. The pressure strip 6 is elongated and has a plurality of locking posts 61 spaced apart on it. During installation, each locking post 61 passes through a through hole 31 and is locked into a connecting hole 214, thereby pressing the scraper 3 between the pressure strip 6 and the inner side of the main body 21, and the scraper 3 partially extends out of the clearance hole 211 along the inclined direction of the inclined surface. In this embodiment, the connecting hole 214 is a stepped hole, and the end of the locking post 61 has a locking cap. During the process of connecting the locking cap and the stepped hole, the two undergo elastic deformation and finally lock together.

[0048] See Figure 5 and Figure 7The outer surface of the second side of the main body 21 is also provided with a groove 215. The wear-resistant part 5 is disposed in the groove 215 and the thickness of the wear-resistant part 5 is greater than the depth of the groove 215. There are two grooves 215, which are located at the two ends of the outer surface of the second side of the main body 21. The grooves 215 are rectangular. The wear-resistant part 5 matches the shape of the groove 215 and is bonded to the groove 215. In this embodiment, the wear-resistant part 5 is made of wear-resistant flocked sheet, and the thickness of the wear-resistant flocked sheet is greater than the depth of the groove 215, so that the wear-resistant flocked sheet can protrude from the groove 215 after being bonded. However, the height of the wear-resistant flocked sheet is usually not higher than the extension height of the scraper 3. In this way, during the cleaning process of the floor cleaning equipment, the scraper 3 (usually made of rubber) and the wear-resistant flocked sheet can maintain stable contact with the ground at the same time.

[0049] See Figure 5 and Figure 6 In this embodiment, the elastic element 4 is an elastic plate, more specifically, a one-piece molded sheet made of plastic material (such as polypropylene, abbreviated as PP) with elasticity. This arrangement not only reduces production costs but also simplifies the shaping of the elastic element. Two elastic plates are provided, each corresponding to one of the two mounting positions 15. The elastic element 4 specifically includes a connecting section 41 and an elastic section 42 connected to each other. The connecting section 41 is adapted to snap into the mounting position 15 to improve the installation stability of the elastic plate. The elastic section 42 is at least partially inclined upward in a direction away from the connecting section 41 so as to form a gap between it and the bottom of the groove of the mounting position 15 when installed. The connecting section 41 specifically includes a first vertical section 411, a horizontal section 412, a second vertical section 413, and a snap-fit ​​section 414 connected in sequence. The first vertical section 411, the horizontal section 412, and the second vertical section 413 are combined to form an "n" shape. The snap-fit ​​section 414 extends from the free end of the second vertical section 413 toward the first vertical section 411. The elastic section 42 extends from the free end of the second vertical section 413 away from the first vertical section 411. In the installed state, the first vertical section 411 is inserted into the limiting hole 153, the snap-fit ​​section 414 is engaged with the limiting retaining rib 154, and the elastic section 42 extends from the first side of the main body 21 and abuts against the inner surface of the first side of the main body 21.

[0050] The installation and disassembly process of the floating cover plate mounting structure described in the above specific embodiment is described below. During installation, firstly, the two elastic elements 4 are respectively snapped into the two mounting positions 15. Then, the two rotating shafts 213 of the cover plate 2, which has been pre-installed with scraper strips 3, are respectively inserted into the two shaft holes 14. First, one rotating shaft 213 is inserted into the circular shaft hole 14, and then the other rotating shaft 213 is slid inward along the elongated shaft hole 14 until the rotating shaft 213 is snapped between the limiting protrusion 141 and one end of the elongated hole. Next, the cover plate 2 is rotated so that the two elastic arms 212 enter the receiving groove 12, and the cover plate 2 is continued to be pivoted and pressed down until the elastic arms 212 produce elastic deformation and complete the snapping between the two second snapping structures 22 and the first snapping structure 13. At this time, the installation is completed, and the cover plate 2 can float up and down under the action of the elastic elements 4.

[0051] During disassembly, an external force is applied to the operating protrusions 23 at the ends of the two elastic arms 212, causing the second arm segment 2122 to undergo elastic deformation and move towards the first arm segment 2121. When the second locking structure 22 moves with the second arm segment 2122 to disengage from the first locking structure 13, the cover plate 2 is pivoted in the opening direction. At this time, the cover plate 2 is opened, and the internal roller brush 7 can be further disassembled. When it is necessary to remove the cover plate 2, with the cover plate 2 open, pull outwards one end of the cover plate 2 corresponding to the side of the elongated hole, so that the rotating shaft 213 located in the elongated hole first disengages from the restriction of the limiting protrusion 141. Then, the rotating shaft 213 on that side is taken out, and the rotating shaft 213 on the other side is pulled out in the same manner. At this time, the disassembly of the cover plate 2 is completed.

[0052] It should be noted that the above preferred embodiments are merely illustrative of the principles of this application and are not intended to limit the scope of protection of this application. Without departing from the principles of this application, those skilled in the art can adjust the above settings to make this application applicable to more specific application scenarios.

[0053] For example, in an alternative embodiment, although the above embodiment is described with the first snap-fit ​​structure 13 being a transverse rib and the second snap-fit ​​structure 22 being a snap-fit ​​protrusion as an example, this is merely exemplary. Those skilled in the art can adjust the specific forms of the first snap-fit ​​structure 13 and the second snap-fit ​​structure 22, as long as the conditions for snap-fit ​​between the two are met. For example, one of the first snap-fit ​​structure 13 and the second snap-fit ​​structure 22 can be a slot or a hole, and the other can be a snap-fit ​​protrusion. The snap-fit ​​between the two is achieved by the snap-fit ​​protrusion snapping into the slot or hole.

[0054] For example, in another alternative embodiment, although the above embodiment is described as forming an elastic support arm 212 by extending outward from the second side of the main body 21 and setting the second snap-fit ​​structure 22 on the second elastic support arm 212, the setting of the elastic support arm 212 is not necessary. In other embodiments, those skilled in the art can also set the second snap-fit ​​structure 22 on the main body 21 of the cover plate 2. In another alternative embodiment, those skilled in the art can also adjust the specific structure of the elastic support arm 212, such as adjusting the V-shaped elastic support arm 212 to a strip shape.

[0055] For example, in another alternative embodiment, the operation protrusion 23 formed on the second arm segment 2122 is only a preferred embodiment, which can facilitate the operator to apply force. However, the operation protrusion 23 is not necessary, and those skilled in the art can choose whether to set it according to the specific application scenario.

[0056] For example, providing two first snap-fit ​​structures 13 and two second snap-fit ​​structures 22 is merely one specific example. In other embodiments, those skilled in the art can provide other numbers of first snap-fit ​​structures 13 and second snap-fit ​​structures 22. For instance, only one pair of first snap-fit ​​structures 13 and second snap-fit ​​structures 22 can be provided, with the receiving groove 12 correspondingly located at the outer center of the mounting groove 11, and the second snap-fit ​​structure 22 located at the second center of the body. Alternatively, three or more pairs of first snap-fit ​​structures 13 and second snap-fit ​​structures 22 can also be provided.

[0057] For example, in another alternative embodiment, the pivotal connection of the cover plate 2 via the pivot 213 is merely an exemplary implementation. Those skilled in the art can make adjustments to adapt the solution to more specific application scenarios. For instance, the pivot 213 can be replaced with a plug-in rod located on the side of the first side of the main body 21, and a socket with ample space can be provided at the bottom of the housing 1 to accommodate the plug-in rod. The pivotal connection of the cover plate 2 is achieved by inserting the plug-in rod into the socket and allowing it to swing relative to the socket. Alternatively, two shaft holes 14 can be provided at both ends of the first side of the main body 21, and two insert shafts can be provided at the bottom of the housing 1. The pivotal connection of the cover plate 2 is achieved through the cooperation of the shaft holes 14 and the insert shafts.

[0058] For example, in another alternative embodiment, the arrangement of one of the two shaft holes 14 on the housing 1 as an elongated hole is not limiting. Those skilled in the art can make adjustments, such as setting both shaft holes 14 as elongated holes or both shaft holes 14 as round holes.

[0059] For example, in another alternative embodiment, the limiting protrusion 141 in the elongated hole is not necessary. Those skilled in the art can choose whether to set the limiting protrusion 141 based on the specific scenario. Of course, if the limiting protrusion 141 is set, the cover plate 2 will have better connection stability.

[0060] For example, in another alternative embodiment, using a plastic elastic plate as the elastic element 4 is merely a preferred embodiment. In other embodiments, those skilled in the art can use other elastic elements 4 to replace the plastic elastic plate, as long as the elastic element 4 can achieve elastic contact with the cover plate 2 so that the cover plate 2 can adaptively float up and down. For example, the elastic element 4 can also be a compression spring, a spring sheet, a torsion spring, an elastic pad, etc. Of course, when the shape is the same, using a polypropylene elastic plate is beneficial for the integrated molding of the shape and the reduction of costs. Those skilled in the art can also use other materials to form the same elastic plate, such as other elastic plastic materials or elastic metal materials.

[0061] For example, although the above description of the elastic element 4 is based on the example of it being fixedly installed at the bottom of the housing 1, the specific arrangement of the elastic element 4 is not fixed. Under the premise that it can be installed at the bottom of the housing 1, those skilled in the art can adjust the specific arrangement of the elastic element 4. For example, the elastic element 4 can also be integrally injection molded with the bottom of the housing 1.

[0062] For example, in another alternative embodiment, the method of providing a mounting position 15 at the bottom of the housing 1 to install the elastic element 4 is merely exemplary. Those skilled in the art can adjust the arrangement of the mounting position 15, or omit the mounting position 15, as long as the elastic element 4 can be effectively installed at the bottom of the housing 1 and elastically abut against the cover plate 2. For example, the mounting position 15 can also be omitted, and the elastic element 4 (such as a compression spring) can be abutted between the inner side of the cover plate 2 and the bottom surface of the housing 1. Furthermore, the mounting position 15 can also be adjusted based on the type of spring. When the elastic element 4 is a compression spring, columns can be provided at the bottom of the housing 1 and the inner side of the cover plate 2 to accommodate the spring; when the elastic element 4 is a torsion spring, a through hole can be provided at the bottom of the housing 1 so that one connecting rod of the torsion spring can be inserted, while the other connecting rod elastically abuts against the inner side of the cover plate 2.

[0063] For example, in another alternative embodiment, although the above embodiment is described using two mounting positions 15 and two elastic elements 4 as examples, the number of mounting positions 15 and elastic elements 4 is not fixed, and those skilled in the art can adjust it based on specific application scenarios. For example, only one mounting position 15 and one elastic element 4 can be provided, or three or more can be provided.

[0064] For example, in another alternative embodiment, the wear-resistant part 5 is not necessary, and those skilled in the art can choose whether or not to provide the wear-resistant part 5. In addition, the groove 215 on the cover plate 2 for attaching the wear-resistant part 5 is merely exemplary, and those skilled in the art can also choose not to provide the groove 215 on the cover plate 2, and directly attach the wear-resistant part 5 to the cover plate 2.

[0065] For example, in another alternative embodiment, the installation position and installation method of the above-mentioned scraper 3 are exemplary and are not the focus of improvement of this application. Those skilled in the art can also fix the scraper 3 to the cover plate 2 using other common installation methods in the art.

[0066] Of course, the alternative implementation methods described above, as well as the alternative implementation methods and preferred implementation methods, can be used in combination to create new implementation methods that are suitable for more specific application scenarios.

[0067] This application also provides a floor cleaning device, which includes a roller brush 7 and the floating cover plate mounting structure described in the above embodiment. Specifically, the floor cleaning device is a sweeping robot. The cover plate 2 is installed on the bottom surface of the robot's housing 1, and the roller brush 7 is installed in the mounting groove 11 on the bottom surface of the housing 1 and partially extends out from the clearance hole 211. A drive motor is also provided inside the housing, and the roller brush 7 is driven to rotate by the drive motor. During the cleaning process, the roller brush 7 sweeps away the dust on the bottom surface, and the scraper 3 on the cover plate 2 shovels the dust into the dust collection box inside the sweeping robot. When the ground is uneven, the cover plate 2 floats up and down under the elastic force of the elastic element 4, thereby ensuring that it is always in close contact with the cleaning surface.

[0068] The ground cleaning equipment of this application can reduce the structural complexity of the equipment by setting a floating cover plate installation structure at the bottom of the housing 1, realize the quick installation and removal of the cover plate 2, and reduce the production and maintenance costs of the equipment.

[0069] Of course, the floor cleaning equipment, such as a sweeping robot, is merely an example. Those skilled in the art can also apply the floating cover mounting structure of this application to other floor cleaning equipment, such as floor scrubbers, sweeping and mopping robots, etc.

For example, any of the claimed embodiments in the claims of this application can be used in any combination.

[0071] The technical solutions of this application have been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
