Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a housing assembly and a cleaning robot. Background Technology

[0002] Intelligent cleaning equipment, especially cleaning robots, is becoming increasingly widely used as an important tool for automated cleaning in modern homes. These devices typically consist of a main body and an openable cover. The main body houses a dustbin, water tank, or other internal components that require regular cleaning or maintenance by the user. For ease of operation, the cover needs to be easily opened; simultaneously, to ensure proper functioning and protect the internal components, the cover must be reliably secured to the main body when closed.

[0003] Currently, there are various methods for fixing the faceplate to the main body of existing cleaning robots, commonly using simple snap-fit ​​structures, magnetic adsorption, or some basic locking designs. These designs can meet the need for faceplate closure and fixation to a certain extent. However, in actual use scenarios, users often need to flip the cleaning robot over, i.e., place it upside down, to clean the bottom roller brush, side brush, or check sensors. In this upside-down state, relying solely on the slight meshing force of traditional snap-fits or the magnetic attraction force to bear the weight of the faceplate itself and the impact of possible vibrations is often unreliable. The faceplate can easily open and fall off accidentally due to gravity, which may not only expose delicate internal components and accumulate dust, but may even cause damage to the faceplate or internal parts upon falling. Utility Model Content

[0004] One objective of this application is to provide a housing assembly and a cleaning robot to solve the technical problem that the inverted faceplate of a cleaning robot is prone to falling off in the related art.

[0005] This application provides a housing assembly, including:

[0006] The main body has an opening;

[0007] A cover for closing the opening;

[0008] The main body and the cover are provided with a locking hole, and the other includes a buckle detachably connected to the locking hole. The locking hole has a mating peripheral surface and a mating end surface. The buckle includes a fastening structure and a limiting structure disposed opposite to each other. The fastening structure is used to abut against the mating end surface when the buckle is connected to the locking hole. The limiting structure is used to abut against the mating peripheral surface when the buckle is connected to the locking hole, so as to limit the fastening structure from disengaging from the mating end surface by the reaction force of the mating peripheral surface.

[0009] Optionally, the fastening structure includes:

[0010] The support portion is vertically connected to the cover.

[0011] An abutting portion is provided at the end of the support portion and extends in a direction away from the limiting structure. The abutting portion is used to abut against the mating end face when the buckle is connected to the buckle hole.

[0012] Optionally, the limiting structure is vertically connected to the face cover and extends partially in a direction away from the fastening structure.

[0013] Optionally, the buckle further includes:

[0014] The first reinforcing part is connected to the fastening structure and extends outward from opposite sides in the width direction of the fastening structure;

[0015] The second reinforcing part is connected to the limiting structure and extends outward from opposite sides in the width direction of the limiting structure, and the first reinforcing part and the second reinforcing part are arranged at intervals relative to each other.

[0016] Optionally, either the first reinforcing part or the second reinforcing part is an arc-shaped rib structure, and the mid-distance between the first reinforcing part and the second reinforcing part is greater than the distance between either end.

[0017] Optionally, the buckle further includes at least one reinforcing rib perpendicular to the face cover, one end of the reinforcing rib being connected to the fastening structure, and the other end of the reinforcing rib being connected to the limiting structure.

[0018] Optionally, the main body is provided with a clearance groove, the clearance groove is located at the edge of the main body, and a portion of the cover is located above the clearance groove.

[0019] Optionally, the cover includes a hinged portion, which is disposed opposite to the clearance groove in the height direction when the cover is connected to the main body. The hinged portion includes a first side and a second side disposed opposite to each other. The first side is closer to the center of the cover than the second side, and the second side is disposed at the edge of the cover. The hinged portion is provided with a hinged surface, which extends obliquely from the first side to the second side.

[0020] When the cover is connected to the main body, the flip-top surface faces the main body, and the direction from the first side to the second side is parallel and in the same direction as the direction from the limiting structure to the fastening structure. The flip-top surface is further away from the main body on the second side than on the first side.

[0021] Optionally, the cover has a symmetrical structure, the flip-top portion is located on the center line of the cover, and at least one buckle or at least one snap hole is provided on either side of the center line of the cover.

[0022] In another aspect, embodiments of this application provide a cleaning robot, including a housing assembly as described in any of the preceding claims.

[0023] The embodiments of this application achieve the following technical effects: The housing assembly of this application uses a limiting structure to abut against the mating circumferential surface, ensuring that the fastening structure remains in contact with the mating end face, significantly enhancing the connection stability of the buckle and the locking hole. Especially when the cleaning robot is inverted, it can effectively prevent the cover from accidentally falling off due to its own weight or vibration. Because the buckle adopts a single fastening structure, the cover can still be detached from the main body while remaining well fixed, rather than locked, thus meeting the user's disassembly and reassembly needs.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0036] In related technologies, cleaning equipment sometimes needs to be inverted or is subject to operating vibration. The housing components often use simple snap-fit ​​structures, magnetic adsorption, or some basic locking designs. These are prone to loosening or being difficult to disassemble when subjected to gravity or vibration, making it difficult to meet the user's needs.

[0037] To address the aforementioned technical problems, this application provides a housing assembly for use in cleaning equipment, such as a cleaning robot. The housing assembly is equipped with a detachable cover to meet the disassembly and assembly requirements of some functional components in the cleaning equipment, such as the dust box and water tank in the cleaning robot. This application uses a cleaning robot as an example for illustration.

[0038] Please refer to the following: Figures 1 to 6In some embodiments, the housing assembly 100 includes a body 10 and a cover 20. The body 10 has an opening 11, and the cover 20 is used to close the opening 11. One of the body 10 and the cover 20 has a locking hole 12, and the other includes a snap fastener 21 detachably connected to the locking hole 12. The locking hole 12 has a mating peripheral surface 122 and a mating end surface 121. The snap fastener 21 includes a fastening structure 211 and a limiting structure 212 disposed opposite to each other. The fastening structure 211 abuts against the mating end surface 121 when the snap fastener 21 is connected to the locking hole 12, and the limiting structure 212 abuts against the mating peripheral surface 122 when the snap fastener 21 is connected to the locking hole 12, so as to limit the fastening structure 211 from disengaging from the mating end surface 121 by the reaction force of the mating peripheral surface 122.

[0039] The structural principle of the housing assembly 100 in this application embodiment is as follows: Please refer to... Figure 2 The housing assembly 100 is the main part supporting the appearance and structure of the cleaning robot 1000, specifically including the main body 10 and the faceplate 20. The main body 10 is the main outer shell structure of the cleaning robot 1000, and it has an opening 11 for accommodating or retrieving internal components, such as the dust box and water tank. (See also...) Figure 3 The cover 20 is used to close the opening 11 and protect the components inside the main body 10.

[0040] Specifically, one of the main body 10 and the face cover 20 is provided with a locking hole 12, and the other includes a buckle 21 detachably connected to the locking hole 12. For example, the locking hole 12 is located on the main body 10, and the buckle 21 is located on the inner side of the face cover 20. Of course, the locking hole 12 can also be located on the face cover 20, and the buckle 21 can be located on the main body 10, achieving the same connection function.

[0041] Please see Figure 6 The locking hole 12 has a mating peripheral surface 122 and a mating end surface 121. The mating peripheral surface 122 is the sidewall of the locking hole 12, while the mating end surface 121 is the bottom of the locking hole 12 or a stepped surface formed therein, for abutting against a part of the latch 21. Exemplarily, the mating peripheral surface 122 and the mating end surface 121 can be two adjacent and intersecting surfaces, or two non-adjacent surfaces that can be extended to intersect. As another example, the portion of the mating peripheral surface 122 near the entrance of the locking hole 12 can be inclined outward to facilitate the connection and disengagement of the latch 21.

[0042] Please see Figure 4 and Figure 5The snap fastener 21 includes a snap-fit ​​structure 211 and a limiting structure 212 disposed opposite to each other. Specifically, the relative positions of the limiting structure 212 and the snap-fit ​​structure 211 on the cover 20 are fixed, and at least the snap-fit ​​structure 211 can produce a certain amount of elastic deformation to meet the requirements of mating and connecting with the snap hole 12. The limiting structure 212 abuts against the mating circumferential surface 122 within the snap hole 12, so that the snap-fit ​​structure 211 remains in contact with the mating end face 121. When the snap fastener 21 is inserted and connected to the snap hole 12, the snap-fit ​​structure 211 abuts against the mating end face 121, providing a locking force in the main vertical direction (i.e., preventing disengagement). At the same time, the limiting structure 212 abuts against the mating circumferential surface 122, and the reaction force applied to the limiting structure 212 by the mating circumferential surface 122 can effectively limit or prevent the snap-fit ​​structure 211 from moving away from the mating end face 121 due to deformation, vibration, or gravity.

[0043] Please see Figure 6 Furthermore, when disassembling the faceplate 20, the operator can apply a force exceeding the locking force of the latch 21 to tilt and lift the faceplate 20. Since the latch 21 uses a single fastening structure 211, and the limiting structure 212 is not connected to the mating end face 121 in the relative position of the fastening structure 211, the line connecting the fastening structure 211 and the limiting structure 212 can be easily deflected in the depth direction of the locking hole 12. For example, when the fastening structure 211 deflects in the direction of disengaging from the locking hole 12, the fastening structure 211 undergoes elastic deformation, disengages from the mating end face 121, and abuts against the mating peripheral surface 122 until it stops abutting against the side wall of the locking hole 12. At this time, the mutual abutting action between the limiting structure 212 and the mating peripheral surface 122 ends simultaneously when the fastening structure 211 stops abutting against the side wall of the locking hole 12, thereby realizing the disassembly of the faceplate 20. Alternatively, when the limiting structure 212 deflects in the direction of disengaging from the locking hole 12, relative movement occurs between the limiting structure 212 and the mating peripheral surface 122 until it finally abuts against the side wall of the locking hole 12. At this time, the limiting structure 212 no longer applies force to the fastening structure 211, and the fastening structure 211 can easily deform and disengage from the mating end face 121 and the mating peripheral surface 122, thereby realizing the disassembly of the cover 20.

[0044] Understandably, in this embodiment of the application, the housing assembly 100 abuts against the mating peripheral surface 122 via the limiting structure 212, ensuring that the fastening structure 211 remains in contact with the mating end surface 121. This significantly enhances the connection stability between the buckle 21 and the locking hole 12, especially when the cleaning robot 1000 is inverted, effectively preventing the face cover 20 from accidentally falling off due to its own weight or vibration. Because the buckle 21 adopts a single fastening structure 211, the face cover 20 can still be detached from the main body 10 while maintaining good fixation, rather than being locked, thus meeting the user's disassembly and reassembly needs.

[0045] Please refer to the following: Figure 5 and Figure 6 In some embodiments, the fastening structure 211 includes a support portion 2111 and an abutment portion 2112. The support portion 2111 is vertically connected to the cover 20. The abutment portion 2112 is disposed at the end of the support portion 2111 and extends in a direction away from the limiting structure 212. The abutment portion 2112 is used to abut against the mating end face 121 when the buckle 21 is connected to the latch hole 12.

[0046] Understandably, the fastening structure 211 may include a support portion 2111 and an abutment portion 2112. The support portion 2111 is connected to the inner surface of the cover 20 approximately perpendicularly, providing structural support for the abutment portion 2112. The abutment portion 2112 is located at the end of the support portion 2111 away from the cover 20 and extends in a direction away from the limiting structure 212, specifically extending outward in a direction perpendicular to or intersecting the extending direction of the support portion 2111. When the latch 21 connects to the latch hole 12, the abutment portion 2112 actually abuts against the mating end face 121, bearing the main locking force.

[0047] In some embodiments, the abutting surface of the abutting portion 2112 may be an inclined slope, abutting against the edge of the mating end face 121. In other embodiments, the abutting surface of the abutting portion 2112 may be a plane, abutting against the mating end face 121. The abutting portion 2112 may also be configured with a guide slope for abutting against the side wall of the latch hole 12 when the abutting portion 2112 enters the latch hole 12, providing guidance for the latch 21.

[0048] In some embodiments, the support portion 2111 and the abutment portion 2112 may generally form a hook-shaped structure or an inverted L-shaped structure. The designer can configure the specific structure of the support portion 2111 and the abutment portion 2112 according to actual experience, and there are no restrictions here.

[0049] In some embodiments, the limiting structure 212 is vertically connected to the cover 20 and extends partially in a direction away from the fastening structure 211.

[0050] Understandably, the limiting structure 212 is also vertically connected to the inner surface of the cover 20, and at least a portion of it extends away from the fastening structure 211, i.e., it extends towards the interior or sidewall of the latch hole 12. The specific structure of the limiting structure 212 allows it to easily contact the mating peripheral surface 122 of the latch hole 12 and generate the necessary reaction force, thereby achieving the limiting function of the fastening structure 211.

[0051] Please refer to the following: Figure 4 and Figure 5In some embodiments, the buckle 21 further includes a first reinforcing portion 213 and a second reinforcing portion 214. The first reinforcing portion 213 is connected to the fastening structure 211 and extends outward on opposite sides of the fastening structure 211 in the width direction. The second reinforcing portion 214 is connected to the limiting structure 212 and extends outward on opposite sides of the limiting structure 212 in the width direction. The first reinforcing portion 213 and the second reinforcing portion 214 are arranged at intervals.

[0052] Understandably, to improve the overall structural strength and stability of the buckle 21 and prevent it from breaking or deforming during use, the buckle 21 may also include a first reinforcing part 213 and a second reinforcing part 214. The first reinforcing part 213 is connected to the fastening structure 211, and exemplarily, may be a connecting support part 2111, extending outward from opposite sides in the width direction of the fastening structure 211. The second reinforcing part 214 is connected to the limiting structure 212 and extends outward from opposite sides in the width direction of the limiting structure 212. The first reinforcing part 213 and the second reinforcing part 214 are arranged relatively spaced apart, respectively enhancing the rigidity of the fastening structure 211 and the limiting structure 212, making the buckle 21 more robust and durable overall.

[0053] In some embodiments, either the first reinforcing part 213 or the second reinforcing part 214 is an arc-shaped rib structure, and the mid-distance between the first reinforcing part 213 and the second reinforcing part 214 is greater than the distance between either end.

[0054] Understandably, either or both of the first reinforcing part 213 and the second reinforcing part 214 can be designed as arc-shaped rib structures. Arc-shaped ribs not only effectively disperse stress and improve strength, but their arc-shaped contours also facilitate the smooth insertion of the snap fastener 21 into the snap hole 12. Furthermore, the mid-distance between the first reinforcing part 213 and the second reinforcing part 214 is greater than the distance between either end, giving the first reinforcing part 213 and the second reinforcing part 214 a longer extension length, thereby improving the structural stability of the snap fastener 21.

[0055] In some embodiments, the buckle 21 further includes at least one reinforcing rib 215 disposed perpendicular to the cover 20, one end of the reinforcing rib 215 being connected to the fastening structure 211, and the other end of the reinforcing rib 215 being connected to the limiting structure 212.

[0056] Understandably, to further enhance the structural strength and integrity of the latch 21, the latch 21 may also include at least one reinforcing rib 215. The reinforcing rib 215 is preferably positioned perpendicular to the cover 20, with one end connected to the fastening structure 211, such as the support portion 2111 of the fastening structure 211, and the other end connected to the limiting structure 212. The reinforcing rib 215 acts like a bridge, connecting the fastening structure 211 and the limiting structure 212, effectively preventing relative deformation between them, greatly enhancing the latch 21's resistance to bending and torsion, and ensuring the long-term reliability of the locking function.

[0057] Please refer to the following: Figure 2 , Figure 3 and Figure 7 In some embodiments, the main body 10 is provided with a relief groove 13, which is located at the edge of the main body 10, and a portion of the cover 20 is located above the relief groove 13.

[0058] Understandably, by providing the clearance groove 13 in this embodiment, the user can apply upward force to the face cover 20 by inserting their finger into the clearance groove 13 on the edge of the main body 10, causing the face cover 20 to be tilted and lifted, so that the buckle 21 disengages from the buckle hole 12 until the face cover 20 is removed, thereby facilitating the user to perform maintenance or replace parts.

[0059] Please include Figure 3 and Figure 7 In some embodiments, the face cover 20 includes a lifting portion 22, which is disposed opposite to the clearance groove 13 in the height direction when the face cover 20 is connected to the body 10. The lifting portion 22 includes a first side 221 and a second side 222 disposed opposite to each other. The first side 221 is closer to the center of the face cover 20 than the second side 222. The second side 222 is disposed at the edge of the face cover 20. The lifting portion 22 is provided with a lifting surface 223, which extends obliquely from the first side 221 to the second side 222.

[0060] When the cover 20 is connected to the main body 10, the lifting surface 223 faces the main body 10. The direction from the first side 221 to the second side 222 is parallel and in the same direction as the direction from the limiting structure 212 to the fastening structure 211. The lifting surface 223 is further away from the main body 10 on the second side 222 than on the first side 221.

[0061] Understandably, when the cover 20 is closed on the main body 10, the direction from the first side 221 to the second side 222 is parallel and in the same direction as the direction from the limiting structure 212 to the fastening structure 211. Furthermore, in this state, the lifting surface 223 on the second side 222 (at the edge) is further away from the main body 10 than on the first side 221 (near the center), forming an outward slope. This allows the user's fingers to naturally rest on the lifting surface 223, and using the torque or gripping point provided by this slope, easily lift the cover 20 upwards, overcoming the locking force of the buckle 21, achieving easy one-handed opening, conforming to ergonomic principles, and improving the user experience.

[0062] In this embodiment of the application, in order to cooperate with the clearance groove 13 on the main body 10, a lifting cover portion 22 is provided on the face cover 20 opposite to the clearance groove 13. The clearance groove 13 is provided on the edge of the main body 10, and its position and shape are configured so that when the main body 10 and the face cover 20 are closed and connected, it can be positioned opposite to the lifting cover portion 22 and accommodate the user's fingers, making it more convenient for the user to remove the face cover 20.

[0063] In some embodiments, the flip-up surface 223 may be an arc surface that extends obliquely from the first side 221 to the second side 222, with the arc surface recessed inward of the cover 20 to create more space for the user's fingers to hook and fasten.

[0064] In some embodiments, the face cover 20 has a symmetrical structure, with the flip-up portion 22 located on the center line of the face cover 20, and at least one buckle 21 or at least one snap hole 12 provided on either side of the center line of the face cover 20.

[0065] Understandably, the face cover 20 can be configured as a symmetrical structure. In this case, the flip-top portion 22 can be located on the symmetrical center line of the face cover 20. At the same time, at least one corresponding buckle 21 or at least one snap hole 12 is provided on either side of the center line of the face cover 20, so that the connection between the face cover 20 and the main body 10 is evenly stressed, the face cover 20 fits the main body 10 more closely, and the installation and removal operation of the face cover 20 is more stable.

[0066] Please refer to the following: Figures 1 to 6 On the other hand, this application provides a cleaning robot 1000, which includes the housing assembly 100 of the above embodiments.

[0067] The main body 10 of the housing assembly 100 has openings 11 in the dust box, water tank and other locations to facilitate the installation and removal of the dust box and water tank. The cover 20 is connected to the main body 10 to cover the openings 11 and protect the internal structure of the cleaning robot 1000.

[0068] Understandably, the cleaning robot 1000 in this embodiment adopts the shell assembly 100 of the above embodiment. The limiting structure 212 abuts against the mating peripheral surface 122, ensuring that the fastening structure 211 remains in contact with the mating end face 121. This significantly enhances the connection stability between the buckle 21 and the locking hole 12, especially when the cleaning robot 1000 is inverted, effectively preventing the face cover 20 from accidentally falling off due to its own weight or vibration. Because the buckle 21 uses a single fastening structure 211, the face cover 20 can still be detached from the main body 10 while remaining well fixed, rather than locked, thus meeting the user's disassembly and reassembly needs.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; under the concept of this utility model, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this utility model as described above. For the sake of brevity, they are not provided in detail; although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
