Description

Technical Field

[0001] This utility model relates to the field of automated cleaning equipment technology, specifically to a cleaning robot. Background Technology

[0002] In the assembly process of cleaning robots in related technologies, the shell and frame are generally connected by screws. In some locations where the shell needs to be frequently disassembled (such as the location where the control module is installed), a snap-fit ​​structure is also used to achieve detachable connection. However, with screw connections, since there are multiple connecting screws at the connection points, each screw needs to be tightened properly during actual operation, making disassembly and installation time-consuming and laborious. On the other hand, with snap-fit ​​structures, the snap-fit ​​structure is prone to breakage during disassembly, resulting in connection failure and affecting the product's performance. Utility Model Content

[0003] This utility model aims to solve one of the technical problems in related technologies to a certain extent. Therefore, this utility model provides a cleaning robot with the advantages of easy disassembly and maintenance.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a cleaning robot, comprising a frame, a shell, and a connecting assembly. The shell covers the frame and includes multiple covers. At least one cover is connected to the frame via the connecting assembly. The connecting assembly includes a first connector and a second connector. One of the first connector and the second connector is connected to the frame, and the other is connected to the corresponding cover. The first connector has a insertion hole, and the second connector has an insertion protrusion corresponding to the insertion hole. The insertion hole and the insertion protrusion are connected in an insertion manner to achieve a detachable connection between the frame and the corresponding cover.

[0005] In this technical solution, the interference fit between the first connector and the second connector enables a stable connection between the outer shell and the frame. Furthermore, the first connector and the second connector can be quickly separated under the action of a preset external force, enabling rapid assembly and disassembly of the frame and the outer shell, thus improving assembly efficiency.

[0010] Furthermore, the interference fit of the first mating part and the second mating part is between 0.5 mm and 2 mm.

[0011] Furthermore, at least one of the first mating part and the second mating part is made of silicone material, and the hardness of the silicone material is between 40° and 60° Shore.

[0012] Furthermore, the frame includes a bottom support plate, a top support plate, and a support frame. The top support plate is located on the top side of the bottom support plate and is spaced apart from the bottom support plate. The top support plate and the bottom support plate are fixedly connected by the support frame. The outer shell includes a top side cover and a bottom side cover. The top side cover covers the outside of the top support plate and the support frame, and the bottom side cover covers the outside of the bottom support plate. The top side cover and the bottom side cover together define an accommodating space. The frame is placed in the accommodating space, and at least one of the top side cover and the bottom side cover is connected to the frame through the connecting assembly.

[0013] Furthermore, the cleaning robot includes a control module, a clean water tank module, a wastewater tank module, a vision module, and a cleaning module.

Detailed Implementation

[0020] 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 are intended to explain this utility model and should not be construed as limiting it.

[0021] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this utility model. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0022] In related technologies, cleaning robots typically connect their outer shell and frame using screws or plastic clips. However, in actual use, screw installation requires tools (electric or manual wrenches), which is time-consuming and labor-intensive, resulting in high labor costs. Furthermore, it requires high precision in screw hole positioning, which can easily lead to hole deviations and situations where screws cannot be installed. Plastic clips are prone to breakage during disassembly and assembly, which can easily lead to the risk of being unable to reinstall them.

[0023] Based on this, one embodiment of the present invention discloses a cleaning robot, see attached drawing. Figures 1 to 9The system includes a frame 20, a housing 30, and at least one connecting component 10. The frame 20 and the housing 30 are connected by the at least one connecting component 10. The connecting component 10 includes a first connector 11 and a second connector 12. One of the first connector 11 and the second connector 12 is connected to the frame 20, and the other is connected to the housing 30. The first connector 11 and the second connector 12 are interference-fitted. The first connector 11 and the second connector 12 can be separated from each other under a preset external force to achieve a detachable connection between the frame 20 and the housing 30.

[0024] The cleaning robot in this embodiment generally includes a frame 20, a shell 30, and multiple functional modules (such as a cleaning module 42, a control module 41, a clean water tank module 43, a wastewater tank module 44, and a vision module 45). The frame 20 is the basic component of the entire device and has mobility. The shell module, cleaning module 42, control module 41, clean water tank module 43, wastewater tank module 44, and vision module 45 are all mounted on the frame 20, as shown in the attached diagram. Figure 1 , 2 As shown.

[0025] In this embodiment, the outer shell 30 is attached to the frame 20 to create a better appearance for the cleaning robot. The outer shell 30 generally includes multiple covers, which are attached to different positions on the frame 20 to enclose different functional modules such as the cleaning module 42, control module 41, clean water tank module 43, wastewater tank module 44, and vision module 45 on the frame 20.

[0026] In this embodiment, at least a portion of the outer casing 30 is connected to the frame 20 via the connecting component 10. In actual installation, not all outer casings 30 need to be connected to the frame 20 using the connecting component 10. As long as one casing 30 is connected to the frame 20 via the connecting component 10, it is considered within the scope of protection of this application. In actual installation, based on actual needs (components requiring frequent disassembly), the casings corresponding to the cleaning module 42, control module 41, wastewater tank module 44, and vision module 45 can be connected to the frame 20 via the connecting component 10.

[0027] For example, in this embodiment, the control module 41 of the cleaning robot needs to be frequently disassembled during production and use to debug and maintain the control module 41. Therefore, in actual setup, the top cover corresponding to the control module 41 can be connected to the frame 20 through the connecting component 10.

[0028] Of course, in some areas where no functional modules are installed, the outer shell and the frame can also be connected by the connecting components. In this case, the outer shell only serves a decorative purpose, improving the overall appearance of the cleaning robot.

[0029] In this embodiment, the connecting component 10 includes a first connector 11 and a second connector 12. The first connector 11 and the second connector 12 are respectively connected to the frame 20 and the outer shell 30. The first connector 11 and the second connector 12 are interlocked in an interference fit. Compared to the screw-connected structure of the outer shell 30 and the frame 20 in related technologies, the interlocking structure of the first connector 11 and the second connector 12 reduces the amount of screw tightening required during connection, making assembly more convenient. Furthermore, compared to the snap-fit ​​structure, the interference fit avoids the problem of ineffective connection caused by breakage or damage to the snap-fit ​​structure.

[0030] In this embodiment, the first connector 11 and the second connector 12 are fitted together with an interference fit. After they are inserted, the connection at the insertion point is a tight fit structure. When disassembly is required, a certain amount of external force is needed to separate the first connector 11 and the second connector 12, thus avoiding unexpected separation of the outer shell 30 and the frame 20 due to misoperation during use.

[0031] In this embodiment, the interference fit of the first connector 11 and the second connector 12 is not specifically limited. In actual settings, the larger the interference fit, the tighter the connection between the first connector 11 and the second connector 12, that is, the more reliable the connection between the first connector 11 and the second connector 12, and the greater the preset tension required for their separation. The smaller the interference fit, the looser the connection between the first connector 11 and the second connector 12, that is, the smaller the preset tension required for their separation. In actual settings, the appropriate interference fit can be set according to the reliability of the connection and the ease of disassembly.

[0032] In this embodiment, the number of connecting components 10 between the outer shell 30 and the frame 20 is not specifically limited. In actual installation, the outer shell 30 and the frame 20 can be connected by only one of the above-mentioned connecting components 10, or they can be connected by multiple connecting components 10, as long as a stable connection between the outer shell 30 and the frame 20 can be achieved.

[0033] This embodiment does not specifically limit the materials of the first connector 11 and the second connector 12. As long as they can achieve an interference fit, in actual installation, one of the first connector 11 and the second connector 12 can be made of a material that can be deformed under a certain pressure. For example, one of the first connector 11 and the second connector 12 can be made of silicone and the other can be made of metal, or both can be made of silicone. Of course, in actual installation, other materials can also be used, such as rubber or plastic.

[0034] In this embodiment, the specific insertion structure of the first connector 11 and the second connector 12 is not specifically limited. In actual installation, it can be set as shaft hole insertion, slot protrusion insertion or other insertion forms.

[0035] In this embodiment, there is no specific limitation on how the first connector 11 and the second connector 12 are connected to the outer shell 30 and the frame 20. In actual installation, the first connector 11 and the second connector 12 can be directly connected to the outer shell 30 or the frame 20, or they can be connected by setting an intermediate component (such as the mounting bracket 40 mentioned in this utility model). In terms of specific connection methods, the first connector 11 and the second connector 12 can be welded, snap-fitted, plugged in, glued, threaded, or connected through connectors to the frame 20 or the outer shell 30. Of course, the first connector 11 and the second connector 12 can also be set as an integral structure with the frame 20 or the outer shell 30.

[0036] In this embodiment, the magnitude of the preset external force that enables the first connector 11 and the second connector 12 to separate is not specifically limited. In actual setup, the preset external force is generally achievable by the operator through their own strength, so that the operator can quickly open the outer shell 30 and the frame 20 connected by the connecting assembly 10.

[0037] As one embodiment of this utility model, see the appendix. Figures 5 to 8 The first connector 11 includes a mating surface opposite to the second connector 12, and a plug hole 111 is formed on the mating surface. The end of the second connector 12 opposite to the mating surface forms a plug protrusion 121, and the plug protrusion 121 and the plug hole 111 are interference fit.

[0038] In this embodiment, the first connector 11 and the second connector 12 are separate components independent of the outer shell 30 and the frame 20. In actual installation, the first connector 11 and the second connector 12 are first connected to the outer shell 30 or the frame 20 respectively, and then the insertion holes 111 and insertion protrusions 121 of the two are arranged opposite to each other to facilitate insertion.

[0039] In actual implementation, only one of the parts where the insertion hole 111 is formed (first mating part) and the part where the insertion protrusion 121 is formed (second mating part) needs to be made of the aforementioned material that can deform under pressure. For example, the first mating part can be made of silicone material, and the other parts of the first connector 11 can be made of non-silicone material (that is, the first connector 11 and the second connector 12 are formed by splicing different materials). Of course, in actual implementation, in order to ensure production efficiency and overall stability of the connector, the material of the same connector (first connector 11 and second connector 12) is generally kept consistent.

[0040] As one embodiment of this utility model, see the appendix. Figure 7 , 8 The insertion hole 111 includes a guide hole 1111 and a mating hole 1112. The insertion protrusion 121 and the mating hole 1112 are interference-fitted. One end of the mating hole 1112 is connected to the first end of the guide hole 1111. The diameter of the guide hole 1111 is larger than the diameter of the mating hole 1112. The diameter of the second end of the guide hole 1111 is larger than the diameter of the first end.

[0041] In this embodiment, the first connector 11 and the second connector 12 are fitted together using a similar shaft hole insertion structure. In actual installation, the insertion hole 111 includes two parts: a guide hole 1111 and a mating hole 1112. See Appendix. Figure 7 The diameter of the guide hole 1111 is larger than the diameter of the mating hole 1112, and the diameter of the guide hole 1111 gradually decreases along the insertion direction of the insertion protrusion 121 (as shown in the figure). With this structural design, even if there is a certain installation error between the outer shell 30 and the frame 20, the mating parts of the first connector 11 and the second connector 12 can be smoothly inserted into each other, which reduces the precision requirements in the assembly process and improves the assembly efficiency.

[0042] In one embodiment of the present invention, at least one of the first connector 11 and the second connector 12 is made of silicone material, and the hardness of the silicone material is between 40° and 60° Shore.

[0043] This embodiment limits the interference fit of the first connector 11 and the second connector 12. It should be noted that the disassembly pull force and assembly pressure required for the same interference fit under different materials are also different. In actual setting, when one of the first mating part and the second mating part is made of silicone (and the hardness of the silicone material is between Shore 40° and 60°, because the tightness relationship produced by the same interference fit is different for silicone materials with different hardness), when the interference fit between the first mating part and the second mating part is set to 1mm, it has a better insertion and removal feel and connection stability.

[0044] Specifically, in one embodiment of this utility model, the diameter of the insertion protrusion 121 is between 3mm and 10mm, and the diameter of the mating hole 1112 is between 2.5mm and 8mm.

[0045] As can be seen, in actual setup, the diameters of the insertion protrusion 121 and the mating hole 1112 can be set to different sizes according to different usage requirements. It can be imagined that the larger the diameters of the insertion protrusion 121 and the mating hole 1112, the larger the corresponding sizes of the first connector 11 and the second connector 12 will be. Of course, the strength of the first connector 11 and the second connector 12 themselves will also be greater. In different connection positions, the first connector 11 and the second connector 12 of different sizes can be selected as needed.

[0046] For example, in areas with larger housing dimensions, larger connectors (first connector 11 and second connector 12) can be used to ensure sufficient connection strength at the connection points; in areas with relatively limited space, smaller connectors (first connector 11 and second connector 12) can be used to facilitate the installation of the connecting assembly 10 and avoid possible interference during the assembly process.

[0047] As one embodiment of this utility model, see the appendix. Figure 6 The diameter of the opening portion of the mating hole 1112 is smaller than the diameter of the mating hole 1112 inside the opening portion. The mating hole 1112 includes a spherical hole segment, and the insertion protrusion 121 includes a spherical protrusion that mates with the spherical hole segment.

[0048] In this embodiment, the diameter of the opening of the mating hole 1112 is relatively small (relative to the diameter of the mating hole 1112 inside the opening). Thus, in actual installation, the mating hole 1112 forms a structure with a bulge in the middle. After the insertion protrusion 121 is inserted into the mating hole 1112, the smaller opening of the mating hole 1112 can block the insertion protrusion 121 from being pulled out of the mating hole 1112, making the insertion of the mating hole 1112 and the insertion protrusion 121 more stable and improving the reliability of the connection between the first connector 11 and the second connector 12.

[0049] In actual installation, the insertion points of the first connector 11 and the second connector 12 can be configured as a spherical mating structure, see Appendix. Figures 6 to 8 The spherical mating structure facilitates insertion, and after insertion, the spherical mechanism itself can prevent the mating parts from loosening and coming off, making the connection more reliable. Moreover, the regular structure of the spherical shape is also easy to process.

[0050] Of course, it is conceivable that, in actual installation, the mating shape of the insertion parts of the first connector 11 and the second connector 12 can also be set as an irregular curved surface structure, such as a combination structure formed by inclined surfaces and arc surfaces.

[0051] As one embodiment of this utility model, see the appendix. Figure 3 The first connector 11 includes a columnar base, one end face of which is formed as a mating surface, and an annular groove is formed on the outer wall of the base for engaging with one of the frame 20 and the housing 30.

[0052] In this embodiment, the first connector 11 is engaged with the frame 20 or the outer shell 30 via the first connecting part 112. For details, please refer to the appendix. Figure 3 A circumferential groove can be provided on the outer wall of the first connector 11, and a plate can be provided on the outer shell 30 or the frame 20. A U-shaped groove is provided on the plate, so that the plate can be inserted into the groove of the first connector 11 through the opening of the U-shaped groove, thereby achieving a quick and stable connection with the first connector 11.

[0053] In one embodiment of this utility model, the second connecting member 12 includes a connecting rod, one end of which is interference-fitted with the first connecting member 11. The connecting rod has a threaded connection portion and a protruding operating portion. The threaded connection portion is used to connect with one of the threads of the frame 20 and the housing 30. The operating portion is used to drive the connecting rod to rotate when subjected to external force.

[0054] In this embodiment, the second connector 12 is threadedly connected to the frame 20 or the outer shell 30. Specifically, a second connecting part 122 can be provided on the second connector 12, wherein the second connecting part 122 can be set as an external thread segment, and a threaded hole corresponding to the external thread segment is provided on the outer shell 30 or the frame 20. The external thread segment and the threaded hole are threadedly engaged to realize the threaded connection between the second connector 12 and the frame 20 or the outer shell 30.

[0055] Furthermore, to facilitate the threaded connection between the second connector 12 and the housing 30 or the frame 20, the second connector 12 of this utility model can also be provided with an easily screw-on hexagonal structure (operating part), see attached drawing. Figure 5 , 8 .

[0056] As one embodiment of this utility model, see the appendix. Figure 3 , 4 The cleaning robot includes a mounting bracket 40, which is fixed on the frame 20 or the outer shell 30. The mounting bracket 40 is provided with a slot corresponding to the annular groove, and the slot and the annular groove are engaged and connected.

[0057] In this embodiment, the first connector 11 is connected to the frame 20 or the outer shell 30 via the mounting bracket 40. By setting the mounting bracket 40, the connection between the frame 20 and the outer shell 30 and the first connector 11 can be achieved without increasing or changing the structure of the frame 20 and the outer shell 30 themselves.

[0058] In this embodiment, when the cleaning robot is actually set up, after the first connector 11 and the second connector 12 in the connecting assembly 10 are connected to the outer shell 30 or the frame 20, when it is necessary to detach the outer shell 30 from the frame 20, it is not necessary to remove the first connector 11 and the second connector 12 from the outer shell 30 or the frame 20 respectively. It is only necessary to separate the plugging and mating parts of the first connector 11 and the second connector 12 from each other. The first connector 11 and the second connector 12 can remain connected to the outer shell 30 or the frame 20. When it is necessary to connect the outer shell 30 and the frame 20, it is only necessary to reconnect the first connector 11 and the second connector 12 to each other.

[0059] In one embodiment of this utility model, the frame 20 includes a bottom support plate 21, a top support plate 22, and a support frame 23. The top support plate 22 is located on the top side of the bottom support plate 21 and is spaced apart from the bottom support plate 21. The top support plate 22 and the bottom support plate 21 are fixedly connected by the support frame 23. The outer shell 30 includes a top side cover and a bottom side cover. The top side cover covers the outside of the top support plate 22 and the support frame 23, and the bottom side cover covers the outside of the bottom support plate. The top side cover and the bottom side cover together define an accommodating space. The frame 20 is placed in the accommodating space, and at least one of the top side cover and the bottom side cover is connected to the frame 20 through the connecting assembly 10.

[0060] The frame in this embodiment includes multiple components distributed vertically. In actual installation, the outer shell is attached to the frame and covers the frame. See attached drawing. Figure 9 This can improve the overall appearance of the cleaning robot.

[0061] The cleaning robot includes a control module 41, a clean water tank module 43, a wastewater tank module 44, a vision module 45, and a cleaning module 42. The control module 41, clean water tank module 43, wastewater tank module 44, and vision module 45 are disposed within the accommodating space. The control module 41 is disposed on the bottom support plate 21 and located in the gap between the bottom support plate 21 and the top support plate 22. The clean water tank module 43, wastewater tank module 44, and vision module 45 are disposed on the top side of the top support plate 22. The cleaning module 42 is disposed on the bottom side of the bottom support plate, and the bottom end of the cleaning module 42 extends to the bottom side of the bottom cover.

[0062] In actual installation, the cleaning robot also includes a top cover 37 on the top side to close the top of the top side cover and improve the overall appearance of the cleaning robot.

[0063] The cleaning robot in this embodiment includes multiple functional modules (control module 41, clean water tank module 43, wastewater tank module 44, vision module 45, and cleaning module 42). In actual setup, a corresponding cover can be set at each corresponding functional module. In this way, when installing and disassembling the functional module, only the corresponding cover needs to be removed, without having to disassemble the entire outer shell. The separate design of the outer shell can improve the efficiency of the functional module's assembly and disassembly.

[0064] The top cover includes a first cover 31, a second cover 32, a third cover 33, and a fourth cover 34. The first cover 31 is disposed between the bottom support plate 21 and the bottom support plate 22. The first cover 31 and the second cover 32 are opposite to each other and are respectively connected to the bottom support plate 21 through the connecting assembly 10. The third cover 33 is disposed on the top side of the third cover 33. The fourth cover 34 is disposed on the top side of the second cover 32 and is opposite to the third cover 33. The third cover 33 and the fourth cover 34 are respectively connected to the top support plate 22 through the connecting assembly 10.

[0065] The bottom cover includes a fifth cover 35 and a sixth cover 36, which are arranged opposite to each other and are respectively connected to the bottom support plate 21 through the connecting assembly 10.

[0066] In this embodiment, the outer shell 30 includes multiple covers, which are assembled together on the vehicle body to form an integral closed structure. In actual installation, each cover can be connected to the vehicle frame through a connecting component.

[0067] In this embodiment, the connecting component 10 is disposed inside the housing, which facilitates the disassembly of the housing 30 and the frame 20 while concealing the connecting component 10, thus improving the overall appearance of the cleaning robot.

[0068] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
