Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning equipment, in particular to a walking assembly and a cleaning equipment. BACKGROUND

[0002] The sweeping robot as a kind of cleaning equipment can automatically complete ground cleaning work in the room.

[0003] The sweeping robot has a walking wheel. For example, the walking wheel can be a universal wheel. The walking wheel can play a guiding auxiliary role in the walking process of the sweeping robot. In the process of sweeping of the sweeping robot, it is inevitable that hair will be entangled on the end cover of the walking wheel in the axial direction. When the hair accumulates more and more on the end cover of the walking wheel, the walking wheel will be jammed, the walking track of the sweeping robot will be disordered, and even the cleaning process will be stopped, which reduces the cleaning effect and affects the user's use experience.

[0004] Therefore, how to avoid the end cover of the walking wheel from being entangled with hair has become a technical problem to be solved. CONTENT OF THE UTILITY MODEL

[0005] The present application provides a walking assembly and a cleaning equipment, which can avoid the jamming of the walking wheel caused by the entanglement of soft debris, to ensure that the cleaning equipment can work normally and the user's use experience, and can ensure the user's visual experience.

[0006] In a first aspect, the present application provides a walking assembly applied to a cleaning equipment. The walking assembly comprises:

[0007] A mounting member configured to be connected with a device main body of the cleaning equipment, the mounting member having a receiving groove;

[0008] A walking wheel arranged in the receiving groove; the walking wheel has an end cover at an axial end, part of the end cover is located in the receiving groove, and there is a gap between the end cover and the mounting member along the axial direction of the end cover; the end cover is connected with the mounting member;

[0009] A filling member arranged in the receiving groove, the filling member being located between the end cover and the mounting member to fill the gap between the end cover and the mounting member.

[0010] The present application can fill the gap between the end cover and the mounting member in the receiving groove through the arrangement of the filling member in the walking assembly, so as to prevent the hair and other soft debris from being entangled on the end cover when they accumulate in the gap between the end cover and the mounting member in the receiving groove, thereby avoiding the jamming of the walking wheel caused by the entanglement of soft debris and reducing the impact on the cleaning process of the cleaning equipment. In this way, the cleaning equipment can work normally, and the user's use experience can be ensured.

[0011] And even if the soft sundries are accumulated into the gap between the end cover and the mounting part in the accommodating groove, they will be sucked into the dust box under the suction of the fan to realize the cleaning of the ground, and the visual experience of the user can be ensured.

[0012] In some embodiments, the end cover comprises an end cover body and a fixing part, the end cover body is located in the accommodating groove and has a gap between the end cover body and the mounting part in the axial direction of the walking wheel; the fixing part is located on the side of the end cover body facing the mounting part and is connected with the mounting part;

[0013] The filling part is located between the end cover body and the mounting part to fill the gap between the end cover body and the mounting part, so as to block the soft sundries such as hair from entering the gap between the end cover body and the mounting part, to prevent the hair from winding on the fixing part to cause the jamming of the walking wheel and the poor visual experience of the user.

[0014] In some embodiments, the fixing part is located in the middle of the end cover body, and the filling part is arranged around at least part of the circumference of the fixing part, so that along the circumference of the fixing part, the filling part can fill at least part of the gap between the end cover body and the mounting part.

[0015] Compared with the filling part being arranged around part of the circumference of the fixing part, when the filling part is arranged around the entire circumference of the fixing part, the filling part can fill the entire gap between the end cover body and the mounting part along the circumference of the fixing part, so as to increase the filling area of the filling part to the gap between the end cover body and the mounting part, and ensure that the filling part has a better filling effect. In this way, the winding of the soft sundries such as hair on the fixing part can be better avoided, so as to prevent the jamming of the walking wheel or the poor visual experience of the user.

[0016] In some embodiments, the filling part has an annular structure arranged around the circumference of the fixing part, so that the filling part can be arranged around the entire circumference of the fixing part, thereby filling the entire gap between the end cover body and the mounting part along the circumference of the fixing part.

[0017] In some embodiments, the end cover body and part of the fixing part jointly define a limiting groove, the opening of the limiting groove faces the filling part, and the filling part is arranged in the limiting groove through the opening.

[0018] Compared with the end cover body not defining a limiting groove with part of the fixing part, when the filling part is arranged in the limiting groove through the opening, during the installation of the filling part and the walking wheel into the accommodating groove, the limiting groove can limit the filling part, so as to ensure that the filling part is in interference fit with the end cover and the mounting part, and the position of the filling part relative to the end cover does not displace too much, so that the filling part can better fill the gap between the end cover body and the mounting part.

[0019] In some embodiments, the part of the filler protrudes from the slot, so that when the walking wheel and the filler are installed into the accommodating slot together, the filler can be in interference fit with the mounting member and the end cover body, thereby filling the gap between the mounting member and the end cover body.

[0020] In some embodiments, the shape of the limiting slot matches the shape of the filler, so that the shape of the limiting slot and the shape of the filler have a high degree of fit, which can enhance the limiting effect of the limiting slot on the filler.

[0021] In some embodiments, along the axial direction of the walking wheel, the fixing part has a large-diameter end and a small-diameter end, the large-diameter end is located on the side of the end cover body facing the mounting member, and the large-diameter end and the end cover body together define a limiting slot;

[0022] The small-diameter end is connected with the mounting member.

[0023] In this way, the end cover body and the large-diameter end together define a limiting slot, which realizes the limiting of the filler, and at the same time, the fixing part can be connected with the mounting member through the small-diameter end, so that the walking wheel can be connected with the mounting member through the end cover, realizing the assembly of the walking wheel in the mounting member.

[0024] In some embodiments, the walking wheel further comprises a wheel body and a wheel shaft, the wheel body is arranged in the accommodating slot, and the wheel body is provided with an end cover body at the end portion in the axial direction, and part of the end cover body is located in the wheel body; along the axial direction of the wheel body, the wheel shaft penetrates the wheel body, the end cover body and the fixing part, and the wheel shaft has a gap with the end cover body and the fixing part, so that the wheel shaft can rotate freely in the end cover body and the fixing part, ensuring that the cleaning equipment can normally walk under the driving of the driving wheel and the assistance of the walking assembly;

[0025] Along the axial direction of the wheel body:

[0026] The wheel body and the mounting member have a gap, and the filler protrudes from the edge of the wheel body and the end cover body.

[0027] By arranging the gap between the wheel body and the mounting member along the axial direction of the wheel body, it can be avoided that the wheel body interferes with the mounting member when the wheel body is arranged in the accommodating slot, affecting the arrangement of the wheel body in the accommodating slot.

[0028] By arranging the filler to protrude from the edge of the wheel body and the end cover body along the axial direction of the wheel body, when the walking wheel and the filler are installed into the accommodating slot together, the filler can be in interference fit with the mounting member and the end cover body, thereby filling the gap between the mounting member and the end cover body.

[0029] In some embodiments, the walking wheel further comprises a wheel body and a wheel shaft, the wheel body is arranged in the accommodating groove, and the wheel body is provided with an end cover body at the axial end; along the axial direction of the wheel body, the wheel shaft penetrates through the wheel body, the end cover body and the fixing part, and the wheel shaft has a gap with the end cover body and the fixing part, so that the wheel shaft can freely rotate in the end cover body and the fixing part, ensuring that the cleaning equipment can normally walk under the driving of the driving wheel and the assistance of the walking assembly.

[0030] The filling piece is bonded with the circumferential outer wall of the end cover body and / or the fixing part.

[0031] Through the bonding of the filling piece with the circumferential outer wall of the end cover body and / or the fixing part, the filling piece can be fixed on the end cover, so that the filling piece, the end cover, the wheel body, the wheel shaft and the like are arranged in the accommodating groove. Compared with the filling piece connected with the end cover by injection molding and the like, when the filling piece is fixed on the end cover by bonding, the cost of the walking assembly can be reduced, so that the walking assembly has the characteristics of low cost and simple structure.

[0032] Compared with the bonding of the filling piece with the circumferential outer wall of the fixing part, when the filling piece is bonded with the end cover body, the side of the end cover body facing the filling piece can be regarded as the bonding surface of the filling piece. The bonding surface of the filling piece is perpendicular to the fixing part, so that even when the end cover rotates around the fixing part relative to the mounting piece, the shear force generated when the end cover rotates will not affect the bonding effect of the bonding piece between the filling piece and the end cover body. In this way, it can be ensured that the filling piece is not easy to fall off from the end cover, so that the filling piece can always be in interference fit with the mounting piece and the end cover, and fill the gap between the end cover in the accommodating groove and the mounting piece, so as to better block the accumulation of hair and other soft sundries in the gap between the end cover in the accommodating groove and the mounting piece, thereby ensuring the user's experience and visual experience.

[0033] In some embodiments, the filling piece is in interference fit with the end cover and the mounting piece, so that the filling piece can fill the gap between the end cover in the accommodating groove and the mounting piece, thereby better blocking the winding of hair and other soft sundries on the connecting part of the end cover and the mounting piece.

[0034] In some embodiments, the filling piece is a flexible structure.

[0035] Compared with the filling piece being a non-flexible structure, when the filling piece is a flexible structure, the filling piece can deform when the filling piece and the walking wheel are installed in the mounting groove, so as to facilitate the installation of the filling piece and the walking wheel in the mounting groove, and realize the interference fit of the filling piece with the end cover and the mounting piece.

[0036] In some embodiments, the filling piece is a nylon fiber piece.

[0037] Compared with other flexible structures, the nylon fiber piece has a material hardness and a better wear resistance effect, so that the walking assembly has a better durability, and the filler still has a better filling effect between the end cover and the mounting piece after long-term use.

[0038] In some embodiments, the walking wheel has two ends in the axial direction, the walking wheel has an end cover at each of the two ends, and a filler is arranged between each of the two end covers and the mounting piece. In this way, the two fillers can respectively fill the gap between the two end covers and the mounting piece in the accommodation groove, so as to block the accumulation of hair and other soft sundries in the gap between the two end covers and the mounting piece in the accommodation groove, thereby ensuring the user's experience and visual experience.

[0039] In a second aspect, the embodiments of the present application also provide a cleaning device, which comprises a device main body and a walking assembly according to any one of the above, and the walking assembly is connected with the device main body.

[0040] Through the arrangement of the walking assembly in the cleaning device, the walking assembly plays a guiding auxiliary role during the walking process of the cleaning device, and can block the accumulation of hair and other soft sundries in the gap between the end cover and the mounting piece in the accommodation groove, thereby ensuring the user's experience and visual experience.

[0061] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0062] The embodiments of the present application provide a cleaning device. The cleaning device can include a sweeping robot, a dust collector and the like cleaning machine with a walking assembly.

[0063] Figure 1 A structural schematic diagram of a cleaning device 100 is shown. Among them, Figure 1 The cleaning device 100 shown in the middle is a sweeping robot. The structure of the cleaning device 100 will be further described below with the sweeping robot as an example. Figure 1 The structure of the cleaning device 100 will be further described below with the sweeping robot as an example.

[0064] Referring to Figure 1 , the cleaning device 100 comprises a device body 1, the device body 1 comprises a casing 11 and internal components. The internal components can be arranged in the casing 11. For example, the internal components can comprise a fan, a roller brush and a dust box 12. Specifically, the bottom surface 111 of the casing 11 can be provided with an opening, and the roller brush arranged in the casing 11 can be partially arranged in the opening, so that the roller brush can be in contact with the ground when rotating relative to the casing 11 to clean the ground.

[0065] When the fan and the dust box 12 are arranged in the casing 11, the fan and the dust box 12 are communicated, and the dust box 12 is communicated with the opening, so that the fan is communicated with the opening through the dust box 12. In this way, when the fan is working, suction can be applied to the opening through the dust box 12, so that the to-be-cleaned objects on the ground can be sucked into the dust box 12 to achieve cleaning of the ground.

[0066] The to-be-cleaned objects can be paper scraps, food debris, soft sundries and the like. The soft sundries can include but are not limited to hair. For example, the soft sundries can also be cotton threads and the like. The to-be-cleaned objects sucked into the dust box 12 through the opening can be collected to facilitate centralized treatment of the to-be-cleaned objects.

[0067] Referring to Figure 1 , the device body 1 further comprises a driving wheel 13. The driving wheel 13 is usually arranged on the bottom surface 111 of the casing 11 and located at both ends of the axial direction of the roller brush. The driving wheel 13 can serve as the driving wheel 13 of the cleaning device 100, and the driving wheel 13 can provide power for the cleaning device 100 to move, turn and the like. For example, the driving wheel 13 can be a roller and the like.

[0068] Referring to Figure 1 , the cleaning device 100 further comprises a walking assembly comprising a mounting member 2 and a walking wheel 3. The mounting member 2 is configured to be connected with the device body 1. For example, the mounting member 2 can be a mounting bracket. The mounting member 2 has a receiving groove 21, and the walking wheel 3 is arranged in the receiving groove 21, so that the walking wheel 3 can be connected with the device body 1 through the mounting member 2.

[0069] The walking wheel 3 is arranged on the bottom surface 111 of the casing 11 together with the driving wheel 13. For example, when the axial direction of the roller brush is parallel to the first direction of the casing 11, the driving wheel 13 can be arranged on both sides of the bottom surface 111 of the casing 11 in the first direction. For example, the walking wheel 3 can be arranged on either side or both sides of the bottom surface 111 of the casing 11 in the second direction. Specifically, when the number of the walking wheel 3 is one, the walking wheel 3 can be arranged on either side of the bottom surface 111 of the casing 11 in the second direction. When the number of the walking wheel 3 is two, the two walking wheels 3 can be arranged on both sides of the bottom surface 111 of the casing 11 in the second direction.

[0070] The first direction refers to the left-right direction of the casing 11, as can be seen in [reference needed]. Figure 1 The x-direction. The second direction is the front-rear direction of the casing 11, which can be seen in [reference]. Figure 1 y direction.

[0071] The bottom surface 111 of the housing 11 refers to the side of the housing 11 facing the ground along a third direction when the cleaning equipment 100 is placed on the ground. The third direction refers to the thickness direction of the housing 11, as shown in [reference needed]. Figure 2 The z-direction. Any two of the x, y, and z directions are perpendicular to each other.

[0072] The walking wheel 3 can serve as the driven wheel of the cleaning device 100, so that when the driving wheel 13 provides power to the cleaning device 100, the walking wheel 3 can play a guiding and assisting role in the movement of the sweeping robot, so that the cleaning device 100 can work normally. For example, the walking wheel 3 can be a swivel wheel.

[0073] It should be noted that the main body 1 of the device can be understood as the structure of the cleaning device 100 excluding the walking components. The above is only a brief introduction to part of the structure of the main body 1 of the device and does not constitute a limitation on the structure included in the main body 1 of the device. For example, the main body 1 of the device may also include an obstacle avoidance device. The obstacle avoidance device can monitor the distance between the cleaning device 100 and obstacles in real time to prevent the cleaning device 100 from hitting obstacles when cleaning the ground. For example, obstacles can be walls, furniture, etc. The structure of the main body 1 of the device can be determined according to the structure of existing cleaning devices 100, and will not be described in detail in the embodiments of this application.

[0074] During the cleaning process of existing cleaning equipment, hair inevitably gets tangled on the end caps of the drive wheels. As the cleaning equipment continues to clean, the hair accumulates more and more on the end caps of the drive wheels. At this point, the drive wheels may become stuck, causing the cleaning equipment to move erratically, or even stopping the cleaning process, reducing the cleaning effect and affecting the user experience. Furthermore, the accumulation of hair on the drive wheels also creates a poor visual experience for the user.

[0075] Therefore, how to prevent hair from getting tangled in the end caps of the wheels has become a technical problem that needs to be solved.

[0076] Therefore, the inventors of this application have studied the reasons why hair gets entangled in the end caps of the wheels. The reasons for hair getting entangled in the end caps of the wheels are explained below with reference to the accompanying drawings.

[0077] Figure 2 A schematic diagram of a walking component is shown.

[0078] See Figure 3When the walking wheel 3 is arranged in the accommodating groove 21 of the mounting member 2, the end cover 31 is usually connected with the mounting member 2. When the walking wheel 3 is arranged in the accommodating groove 21 of the mounting member 2 and connected with the mounting member 2, there is a gap Q between the end cover 31 of the walking wheel 3 and the mounting member 2 in the accommodating groove 21. Since the hair on the ground is usually in a scattered state, when the cleaning device 100 is sweeping, the hair is easy to accumulate in the gap Q and entangle on the connecting part of the end cover 31 and the mounting member 2. When the hair entangles more and more on the end cover 31, it will cause the walking wheel 3 to jam.

[0079] Therefore, the embodiment of the present application provides a walking assembly applied to the cleaning device 100. By arranging the filler 6 in the walking assembly, the gap Q between the end cover 31 and the mounting member 2 in the accommodating groove 21 can be filled, so as to prevent the hair and other soft sundries from entangling on the end cover 31 when they accumulate in the gap Q between the end cover 31 and the mounting member 2 in the accommodating groove 21, thereby avoiding the jamming of the walking wheel 3 caused by the entanglement of the soft sundries and reducing the influence on the cleaning process of the cleaning device 100. In this way, the normal working of the cleaning device 100 can be ensured, and the user's experience can be ensured.

[0080] Moreover, even if the soft sundries accumulate in the gap Q between the end cover 31 and the mounting member 2 in the accommodating groove 21, they will be sucked into the dust box 12 under the suction of the fan, so as to realize the sweeping of the ground, and the visual experience of the user can be ensured.

[0081] The structure of the walking assembly will be further described below in combination with the drawings and embodiments.

[0082] Figure 4 and Figure 5 The structure schematic diagrams of the walking assembly under different visual angles are provided. Figure 3 It is shown that Figures 3 to 5 the cross-sectional view of the walking assembly in the A-A direction in the embodiment.

[0083] Referring to Figure 3 As described above, the walking assembly comprises the mounting member 2 and the walking wheel 3 arranged in the accommodating groove 21. The walking wheel 3 has the end cover 31 at the axial end. Part of the end cover 31 is located in the accommodating groove 21 and has the gap Q between the end cover 31 and the mounting member 2 in the axial direction of the walking wheel 3, so as to facilitate the assembly of the walking wheel 3 in the accommodating groove 21. The end cover 31 is connected with the mounting member 2, so that when the walking wheel 3 is arranged in the accommodating groove 21, the connection with the mounting member 2 is realized through the end cover 31.

[0084] Referring to Figure 5 and Figure 4To achieve the connection of the mounting member 2 and the device body 1, in some embodiments, the walking assembly can further include a connecting member 4. One end of the connecting member 4 is connected with the mounting member 2, and the other end is connected with the device body 1, so that the mounting member 2 is connected with the device body 1 through the connecting member 4. For example, the connecting member 4 can be a connecting shaft or the like.

[0085] It should be noted that the connection mode of the connecting member 4 with the mounting member 2 and the device body 1 can be determined according to the existing cleaning device 100 such as a sweeping robot, and will not be described in detail in the embodiments of the present application.

[0086] In some embodiments, the walking assembly can further include a shock-absorbing pad 5. The shock-absorbing pad 5 is sleeved on the circumference of the connecting member 4 and located between the mounting member 2 and the device body 1, so that the cleaning device 100 has a shock-absorbing function when the walking assembly is connected with the device body 1 through the mounting member 2. As an example, when the cleaning device 100 vibrates due to uneven ground during walking, the shock-absorbing pad 5 can play a buffering role and absorb the vibration of the cleaning device 100 to ensure the stability of the cleaning device 100 during walking.

[0087] For example, the shock-absorbing pad 5 can have a ring structure so as to be sleeved on the circumference of the connecting member 4.

[0088] Referring to Figure 5 and Figure 5 , the walking assembly further includes a filling member 6. The filling member 6 is arranged in the accommodating groove 21. The filling member 6 is located between the end cover 31 and the mounting member 2 to fill the gap Q between the end cover 31 and the mounting member 2.

[0089] By filling the gap Q between the end cover 31 and the mounting member 2 in the accommodating groove 21 with the filling member 6, the accumulation of fine and soft sundries such as hair in the gap Q between the end cover 31 and the mounting member 2 in the accommodating groove 21 can be blocked, so as to prevent the fine and soft sundries from winding around the connection part of the end cover 31 and the mounting member 2, thereby avoiding the jamming of the walking wheel 3 due to the winding of the fine and soft sundries. In this way, the cleaning device 100 can walk along the normal walking track, so that the cleaning device 100 can work normally and the user's experience can be ensured.

[0090] Moreover, even if the fine and soft sundries accumulate in the gap Q between the end cover 31 and the mounting member 2 in the accommodating groove 21, the fine and soft sundries will not wind around the end cover 31 and will be sucked into the dust box 12, so as to achieve the cleaning of the ground, and the visual experience of the user can be ensured.

[0091] Continuing to refer to Figure 6The filler 6 is in interference fit with the end cap 31 and the mounting member 2, i.e. the filler 6 is in tight fit with the end cap 31 and the mounting member 2, and when the filler 6 is arranged between the end cap 31 and the mounting member 2, the filler 6 can have interference (i.e. interference fit) with the end cap 31 or the mounting member 2. In this way, the filler 6 can fill the gap Q between the end cap 31 and the mounting member 2 in the accommodating groove 21, so as to better prevent the soft sundries such as hair from winding around the connecting part of the end cap 31 and the mounting member 2.

[0092] Specifically, the thickness of the filler 6 should be greater than the gap Q between the end cap 31 and the mounting member 2 in the accommodating groove 21, so as to ensure that when the filler 6 is arranged between the end cap 31 and the mounting member 2, the filler 6 can realize the interference fit with the end cap 31 and the mounting member 2.

[0093] The filler 6 can be a flexible structure. The flexible structure can be understood as a structure that is easy to deform when being pressed. Alternatively, the filler 6 can also be a non-flexible structure. The non-flexible structure can be understood as a structure that cannot or is difficult to deform when being pressed.

[0094] Compared with the case that the filler 6 is a non-flexible structure, when the filler 6 is a flexible structure, the filler 6 can deform when the filler 6 and the walking wheel 3 are installed in the mounting groove, so as to facilitate the installation of the filler 6 and the walking wheel 3 in the mounting groove, and realize the interference fit of the filler 6 with the end cap 31 and the mounting member 2.

[0095] When the filler 6 is a flexible structure, the filler 6 can be a nylon fiber piece, silica gel, foam or other flexible structures. For example, the material of the nylon fiber piece can be nylon fluff or the like. Compared with other flexible structures, the nylon fiber piece has a hard material and good wear resistance effect, so that the filler 6 still has a good filling effect on the gap Q between the end cap 31 and the mounting member 2 after the walking assembly is used for a long time, and the walking assembly has good durability.

[0096] Figure 1 An exploded view of a walking assembly is shown Figure 5 .

[0097] Referring to Figure 6 and Figure 5 , in some embodiments, the end cap 31 includes an end cap body 311 and a fixing part 312. The end cap body 311 is located in the accommodating groove 21 and has a gap in the axial direction of the walking wheel 3 with the mounting member 2. The gap Q between the end cap 31 and the mounting member 2 refers to the gap between the end cap body 311 and the mounting member 2 in the axial direction of the walking wheel 3. Hereinafter, the gap between the end cap body 311 and the mounting member 2 in the axial direction of the walking wheel 3 is denoted as the gap Q.

[0098] The fixing portion 312 is located on the side of the end cover body 311 facing the mounting member 2 and is connected with the mounting member 2. In this way, the end cover 31 can be connected with the mounting member 2 through the fixing portion 312. The fixing portion 312 can be understood as the connecting part of the end cover 31 and the mounting member 2.

[0099] With reference to the foregoing Figure 6 and Figure 5 , it should be understood that, since the walking wheel 3 is arranged in the accommodating groove 21 and the end cover 31 is located at the axial end of the walking wheel 3 and is connected with the mounting member 2, the “fixing portion 312 is located on the side of the end cover body 311 facing the mounting member 2” mentioned above means that the fixing portion 312 is located on the side of the end cover body 311 facing away from the walking wheel 3, so that the end cover 31 can be connected with the mounting member 2 through the fixing portion 312.

[0100] For example, the fixing portion 312 can be a shaft protruding from the side of the end cover 31 facing away from the walking wheel 3, so that when the end cover body 311 is located in the accommodating groove 21, the fixing portion 312 can be arranged in the mounting member 2 to achieve connection with the mounting member 2, and at the same time, the position of the fixing portion 312 relative to the mounting member 2 can be fixed.

[0101] With reference to the foregoing Figure 5 , the filler 6 is located between the end cover body 311 and the mounting member 2 to fill the gap Q between the end cover body 311 and the mounting member 2, so as to block fine sundries such as hair from entering the gap Q between the end cover body 311 and the mounting member 2, thereby preventing the hair from winding around the fixing portion 312 to cause the walking wheel 3 to jam and the user's poor visual experience.

[0102] It should be noted that the filler 6 can be in interference fit with the end cover body 311 and the mounting member 2 to fill the gap Q between the end cover body 311 and the mounting member 2.

[0103] With reference to the foregoing Figure 6 and Figure 6 , in some embodiments, the fixing portion 312 is located in the middle of the end cover body 311. The middle of the end cover body 311 refers to the middle region of the end cover body 311. The middle region includes the center of the end cover body 311 and has a distance from the outermost edge of the end cover body 311 in the radial direction of the end cover body 311. Moreover, the filler 6 can be arranged around at least part of the circumferential direction of the fixing portion 312. In this way, along the circumferential direction of the fixing portion 312, at least part of the gap Q between the end cover body 311 and the mounting member 2 can be filled by the filler 6.

[0104] The “filler 6 can be arranged around at least part of the circumferential direction of the fixing portion 312” mentioned above means that the filler 6 can be arranged around part of the circumferential direction of the fixing portion 312, or the filler 6 can also be arranged around the entire circumferential direction of the fixing portion 312.

[0105] Compared with the case that the filler 6 is arranged around the partial circumferential direction of the fixing portion 312, when the filler 6 is arranged around the entire circumferential direction of the fixing portion 312, the filler 6 can fill the gap Q between the end cover body 311 and the mounting member 2 along the entire circumferential direction of the fixing portion 312, so as to increase the filling area of the filler 6 to the gap Q between the end cover body 311 and the mounting member 2, and ensure that the filler 6 has a better filling effect. In this way, it can better avoid the phenomenon that the soft sundries such as hair are wound on the fixing portion 312, causing the walking wheel 3 to be stuck or causing the user to have a poor experience.

[0106] For example, continuing to refer to Figure 5 , the filler 6 can have an annular structure that is sleeved around the circumferential direction of the fixing portion 312, so that the filler 6 can be arranged around the entire circumferential direction of the fixing portion 312, thereby filling the gap Q between the end cover body 311 and the mounting member 2 along the entire circumferential direction of the fixing portion 312.

[0107] Continuing to refer to Figure 6 and Figure 5 , in some embodiments, the end cover body 311 and the partial fixing portion 312 jointly define a limiting groove 313, and the slot of the limiting groove 313 faces the filler 6, and the filler 6 is arranged in the limiting groove 313 through the slot. Specifically, one side of the end cover body 311 facing the filler 6 can form an inner concave surface 3111. When the fixing portion 312 is arranged on the inner concave surface 3111, the end cover body 311 and the fixing portion 312 jointly define a limiting groove 313. The inner concave surface 3111 can serve as the groove bottom of the limiting groove 313.

[0108] Alternatively, in other embodiments, one side of the end cover body 311 facing the filler 6 can also not form an inner concave surface 3111, that is, the end cover body 311 does not define a limiting groove 313 with the partial fixing portion 312.

[0109] Compared with the case that the end cover body 311 does not define a limiting groove 313 with the partial fixing portion 312, when the filler 6 is arranged in the limiting groove 313 through the slot, the limiting groove 313 can limit the filler 6 during the process of installing the filler 6 and the walking wheel 3 into the accommodating groove 21, so as to ensure that the filler 6 is in interference fit with the end cover 31 and the mounting member 2, and the position of the filler 6 relative to the end cover 31 does not displace too much, so that the filler 6 can better fill the gap Q between the end cover body 311 and the mounting member 2.

[0110] Hereinafter, the structure of the walking assembly is further described by taking the case that the end cover body 311 and the partial fixing portion 312 jointly define a limiting groove 313 as an example.

[0111] Continuing to refer to Figure 5When the filler 6 is arranged in the limiting groove 313 through the slot, part of the filler 6 extends out of the slot, so that when the filler 6 is installed into the accommodating groove 21 together with the walking wheel 3, the filler 6 can be in interference fit with the mounting member 2 and the end cover body 311, thereby filling the gap Q between the mounting member 2 and the end cover body 311.

[0112] With reference to the foregoing Figure 6 and Figure 5 In some embodiments, the shape of the limiting groove 313 can be matched with the shape of the filler 6, i.e., the shape of the limiting groove 313 can be the same as or similar to the shape of the filler 6. For example, the shape of the filler 6 is annular, and the shape of the limiting groove 313 is also annular. It should be understood that, in order to facilitate the arrangement of the filler 6 in the limiting groove 313, the size of the limiting groove 313 should be slightly larger than the size of the filler 6, so as to avoid excessive displacement of the filler 6 in the limiting groove 313.

[0113] By limiting the shape of the limiting groove 313 as described above, the shape of the limiting groove 313 can have a higher degree of fit with the shape of the filler 6, and the limiting effect of the limiting groove 313 on the filler 6 can be enhanced.

[0114] With reference to the foregoing Figure 6 and Figure 5 In the axial direction of the walking wheel 3, the fixing portion 312 has a large-diameter end 3121 and a small-diameter end 3122. It should be understood that the radial dimension of the large-diameter end 3121 is larger than the radial dimension of the small-diameter end 3122. The radial dimension can include diameter or radius.

[0115] The large-diameter end 3121 is located on the side of the end cover body 311 facing the mounting member 2 and cooperates with the end cover body 311 to define the limiting groove 313. The small-diameter end 3122 is connected to the mounting member 2. Since the walking wheel 3 is arranged in the accommodating groove 21, and the end cover 31 is located at the axial end of the walking wheel 3 and connected to the mounting member 2, the "large-diameter end 3121 is located on the side of the end cover body 311 facing the mounting member 2" mentioned above means that the large-diameter end 3121 is located on the side of the end cover body 311 away from the walking wheel 3. At this time, compared with the large-diameter end 3121, the small-diameter end 3122 is closer to the mounting member 2. In this way, the end cover body 311 and the large-diameter end 3121 cooperatively define a limiting groove 313, which achieves the limiting of the filler 6, and the fixing portion 312 can be connected to the mounting member 2 through the small-diameter end 3122, so that the walking wheel 3 can be connected to the mounting member 2 through the end cover 31, and the assembly of the walking wheel 3 in the mounting member 2 is achieved.

[0116] With reference to the foregoing Figure 5In some embodiments, the mounting member 2 can be provided with a groove body 22 in communication with the accommodating groove 21 at a position opposite to the small-diameter end 3122, so that the small-diameter end 3122 penetrates through the accommodating groove 21 and extends into the groove body 22 to be connected with the mounting member 2 and fixed relative to the mounting member 2. That is, when the walking wheel 3 moves relative to the mounting member 2 to drive the cleaning device 100 to move and turn, the position between the end cap 31 and the mounting member 2 is fixed, and the end cap 31 is not prone to rotating relative to the mounting member 2.

[0117] It should be noted that, Figure 7 The above is only a schematic of the connection mode of the fixing portion 312 and the mounting member 2, and does not constitute a limitation on the connection mode of the fixing portion 312 and the mounting member 2. That is, the fixing portion 312 and the mounting member 2 can be connected by using any related connection mode in the existing cleaning device 100, which will not be described herein again.

[0118] Figure 2 An explosion of a walking assembly is shown Figure 7 .

[0119] Referring to Figure 5 , the walking wheel 3 further includes a wheel body 32 and a wheel shaft 33, and the wheel body 32 is arranged in the accommodating groove 21. Moreover, the wheel body 32 is provided with an end cap body 311 at an axial end, and part of the end cap body 311 is arranged in the wheel body 32. For example, the wheel body 32 is provided with a groove at an axial end, and the end cap body 311 is arranged in the groove, so that part of the end cap body 311 is arranged in the wheel body 32.

[0120] Referring to Figure 7 and Figure 5 , the wheel shaft 33 penetrates through the wheel body 32, the end cap body 311 and the fixing portion 312 along the axial direction of the wheel body 32. Moreover, the wheel shaft 33 has a gap with the end cap body 311 and the fixing portion 312. That is, the wheel shaft 33 is in a gap fit with the end cap body 311 and the fixing portion 312, so that the wheel shaft 33 can rotate freely in the end cap body 311 and the fixing portion 312, and ensure that the cleaning device 100 can normally walk under the driving of the driving wheel 13 and the assistance of the walking assembly. The axial direction of the wheel body 32 can refer to the w direction in Figure 7 and Figure 5 . The w direction can be parallel to the first direction (x direction) mentioned above.

[0121] Specifically, the wheel body 32 has a through hole penetrating the wheel body 32 at two axially opposite sides. The end cover body 311 can be a circular ring structure, and the fixing portion 312 can be a sleeve portion coaxially arranged with the circular ring structure and the wheel body 32. Moreover, the sleeve portion is located on the side of the end cover body 311 away from the wheel body 32. In this way, the wheel shaft 33 can penetrate the wheel body 32, the end cover body 311 and the fixing portion 312 along the axial direction of the wheel body 32.

[0122] Continuing to refer to Figure 5 , along the axial direction (w direction) of the wheel body 32:

[0123] The wheel body 32 and the mounting member 2 have a gap therebetween, and the filler 6 protrudes from the edge of the wheel body 32 and the end cover body 311. It should be noted that the edge of the wheel body 32 referred to here refers to the outermost edge of the wheel body 32 in the axial direction (w direction). Correspondingly, the edge of the end cover body 311 referred to here refers to the outermost edge of the wheel body 32 in the axial direction (w direction).

[0124] It should be noted that since part of the end cover body 311 is located in the wheel body 32, the gap between the wheel body 32 and the mounting member 2 along the axial direction (w direction) of the wheel body 32 is smaller than the gap Q between the mounting member 2 and the end cover body 311.

[0125] By arranging the gap between the wheel body 32 and the mounting member 2 along the axial direction (w direction) of the wheel body 32, the wheel body 32 can be prevented from interfering with the mounting member 2 when arranged in the accommodating groove 21, thereby affecting the arrangement of the wheel body 32 in the accommodating groove 21.

[0126] By arranging the filler 6 to protrude from the edge of the wheel body 32 and the end cover body 311 along the axial direction (w direction) of the wheel body 32, when the filler 6 is installed together with the road wheel 3 in the accommodating groove 21, the filler 6 can be in interference fit with the mounting member 2 and the end cover body 311, thereby filling the gap Q between the mounting member 2 and the end cover body 311.

[0127] Continuing to refer to Figure 7 and Figure 5 In some embodiments, when the filler 6 is arranged between the end cover body 311 and the mounting member 2, the filler 6 can also be bonded to the circumferential outer wall of the end cover body 311 and / or the fixing portion 312. Specifically, the filler 6 can be bonded to the circumferential outer wall of the end cover body 311 and / or the fixing portion 312 by a bonding member. The bonding member can be adhesive or the like.

[0128] The filling piece 6 is fixed on the end cover 31 by being bonded with the circumferential outer wall of the end cover body 311 and / or the fixing portion 312. In this way, the filling piece 6 can be conveniently arranged in the accommodating groove 21 together with the end cover 31, the wheel body 32, the wheel shaft 33 and the like. Moreover, compared with the filling piece 6 being connected with the end cover 31 by injection molding or the like, when the filling piece 6 is fixed on the end cover 31 by bonding, the cost of the walking assembly can be reduced, so that the walking assembly has the characteristics of low cost and simple structure.

[0129] It should be noted that the above-mentioned "the filling piece 6 can also be bonded with the circumferential outer wall of the end cover body 311 and / or the fixing portion 312" means that the filling piece 6 can be bonded with the end cover body 311, or the filling piece 6 can be bonded with the circumferential outer wall of the fixing portion 312, or the filling piece 6 can also be bonded with the circumferential outer wall of the end cover body 311 and the fixing portion 312 at the same time.

[0130] Compared with the filling piece 6 being bonded with the circumferential outer wall of the end cover body 311 and the fixing portion 312 at the same time, when the filling piece 6 is bonded with the circumferential outer wall of the end cover body 311 or the fixing portion 312, the bonding area of the filling piece 6 and the end cover 31 can be reduced, so as to facilitate the bonding of the filling piece 6 and the end cover 31.

[0131] Although the wheel body 32 of the walking wheel 3 is relatively fixed with the mounting member 2 during rotation, the end cover 31 can also rotate relative to the mounting member 2 under the action of a larger force. When the filling piece 6 is bonded with the circumferential outer wall of the fixing portion 312, if the end cover 31 rotates relative to the mounting member 2 around the fixing portion 312, the shear force generated by the rotation of the end cover 31 will cause the bonding member to separate from the circumferential outer wall of the fixing portion 312 or the inner wall 61 of the filling piece 6, which will affect the stability of the bonding of the filling piece 6 and the end cover 31, and may cause the filling piece 6 to fall off from the end cover 31.

[0132] Compared with the adhesion of the filler 6 and the circumferential outer wall of the fixing portion 312, when the filler 6 is adhered to the end cover body 311, the side of the filler 6 facing the end cover body 311 will be adhered. The side of the end cover body 311 facing the filler 6 can be regarded as the adhesion surface of the filler 6. The adhesion surface of the filler 6 is perpendicular to the fixing portion 312, so that even when the end cover 31 rotates around the fixing portion 312 relative to the mounting member 2, the shear force generated when the end cover 31 rotates will not affect the adhesion effect of the adhesive between the filler 6 and the end cover body 311. In this way, it can be ensured that the filler 6 is not easy to fall off the end cover 31, so that the filler 6 can be better fixed on the end cover 31, so that the filler 6 can always maintain an interference fit with the mounting member 2 and the end cover 31, fill the gap Q between the end cover 31 in the accommodation groove 21 and the mounting member 2, and better block the accumulation of hair and other soft sundries in the gap Q between the end cover 31 in the accommodation groove 21 and the mounting member 2, thereby ensuring the user's experience and visual experience.

[0133] Continuing to refer to Figure 7 and ​ , the walking wheel 3 has two ends in the axial direction, the walking wheel 3 has an end cover 31 at both ends, and the two end covers 31 are provided with a filler 6 between the mounting member 2. In this way, the two fillers 6 can respectively fill the gap Q between the two end covers 31 in the accommodation groove 21 and the mounting member 2, so as to block the accumulation of hair and other soft sundries in the gap Q between the two end covers 31 in the accommodation groove 21 and the mounting member 2, thereby ensuring the user's experience and visual experience.

[0134] The embodiments of the present application provide a cleaning device 100 including a device main body 1 and a walking assembly as any of the above embodiments, the walking assembly is connected with the device main body 1, so as to play a guiding auxiliary role in the walking process of the cleaning device 100, and can block the accumulation of hair and other soft sundries in the gap Q between the end cover 31 in the accommodation groove 21 and the mounting member 2, thereby ensuring the user's experience and visual experience.
